Niran Baruch -- Chief Financial Officer
Thank you, Shabtai, and hello everyone. As usual, on today's call, we will be referring to both GAAP and non-GAAP financial results. The earnings press release that we issued earlier this morning contains a reconciliation of the supplemental non-GAAP financial information that I will be discussing on this call. Revenues for the second quarter were $53.5 million, an increase of 8.1% compared to the second quarter last year. Services revenues for the second quarter were $17.1 million, accounting for 32.1% of total revenues. The amount of deferred revenues as of June 30, 2020 was $65.1 million compared to $55.8 million as of June 30, 2019. Revenues by geographical region for the quarter were split as follows: North America, 41%; Central and Latin America, 7%; EMEA, 40%; and Asia-Pacific, 12%. Our top 15 customers in aggregate represented 60% of revenues in the second quarter; of which, 42% are attributed to our nine largest distributors.
Gross margin for the quarter was 66.7% compared to 63.3% in Q2 2019. Non-GAAP gross margin for the quarter was 66.9% compared to 63.5% in Q2 2019. Operating income for the quarter was $8.8 million, compared to an operating income of $5.9 million in Q2 2019. On a non-GAAP basis, quarterly operating income was $10.7 million or 20.1% of revenues, compared to an operating income of $7 million in Q2 2019. Net income for the quarter was $6.6 million or $0.21 per share, compared to net income of $4.8 million or $0.16 per share in Q2 2019. On a non-GAAP basis, quarterly net income was $10.5 million or $0.32 per share, compared to net income of $6.8 million or $0.22 per share in Q2 2019.
During the quarter, the company raised $85.4 million in net proceeds from the public offering of 2.6 million ordinary shares at a purchase price of $35 per share. At the end of June 2020, cash, cash equivalents and bank deposits totaled $170.4 million. Days sales outstanding as of June 30, 2020 were 51 days. Operating cash flow generated during the quarter was $10.7 million.
Now, to providing an update on our guidance, we reiterate our guidance for revenues for 2020 to be in the range of $214 million to $222 million. We're now raising our guidance for non-GAAP diluted earnings per share to be in the range of $1.18 to $1.24, compared to the previous range of $1.09 to $1.13 that we updated following the close of the first quarter 2020.
I will now turn the call back over to Shabtai.
Shabtai Adlersberg -- President and Chief Executive Officer
Thank you, Niran. We're very pleased to report strong financial results for the second quarter 2020. As stated earlier in our financial release, we enjoyed good business momentum in the quarter, both in the enterprise space and the service provider space. There is no question in our markets these days, the team collaboration is where the action is when it comes to enterprise communication platforms, primarily because of the fact that the pandemic forced enterprises to move employees to work from home and roll out collaboration systems like Microsoft Teams, which end users found to be no longer just interesting, but clearly indispensable. It must still, if you want to preserve business continuity and recover fast from this corona crisis. And so, UCaaS as a cloud service and Collaboration became key to business resilience and have taken center stage in the newly evolving digital workplace.
Now, let me touch on some recent team collaboration market data that reinforces these statements. According to Nemertes, a global research-based advisory and consulting firm, team collaboration use has dramatically grown in past few months. It says that 42% of enterprises currently have more than one team collaboration application in use. Obviously, this number is growing on an ongoing basis. According to Nemertes, Microsoft Teams is the clear leader at 40.3%, [Phonetic] followed by Cisco Webex Teams at 27%; Slack at 9%; Google Chat at 8.5%.
In another example, data from Aternity, an application monitoring company, shows that between February 17 to June 14 this year, Microsoft Teams' use grew almost 900%, while Zoom has grown 680%. More data points from a global study of more than 525 organization found that 91% are going to -- over the organization now support work-from-home, up from 63% prior to the pandemic. And of the total workforce, 72% are now home-based compared with just 34% before the pandemic. Obviously, video conferencing has emerged as the core technology to ensure work-from-home, and nowadays, more than 91% of companies use it to support it and nearly 30% says that they will use video for all of their meetings. As a result, we have experienced in the second quarter growth in most of the major market segments we participate in, including the UCaaS market, the Contact Center market, and the service provider all-IP migration market.
Underlying our success in the second quarter of 2020 is the financial performance. Let me refer to specific financial parameters. Revenue growth, we continue to deliver on our stated guidance to grow revenue this year by 9% delivering 8.1% growth in the second quarter; growth brought our first half 2020 growth to 9.9% growth over the same period in 2019. Growth was very strong in UC-SIP, which grew well above 20%. However, decline of about -- above 15% in gateway revenues and decline of close to $1 million in technology revenue have limited the overall quarterly revenue to 8.1% as stated. Service revenues, growth over the year ago quarter was 3%. However, taking into account seasonality in quarterly services revenue and the fact that we have reported growth of 25% year-over-year for the first quarter of this year, this basically puts us in an average services revenue growth of 13.2% in the first half of 2020.
Gross margin expansion, we keep focusing on growing our software products and solutions versus hardware offerings, turning the company to increasingly become a communication software company. Software products in the touch [Phonetic] services grew to about 35% of total revenue in the quarter, compared to just 25% in the year ago quarter. Specifically, in the second quarter, we grew 50% above the year ago quarter. This by the mix of software products this quarter allowed us to improve gross margin to 66.9% as compared to 66.1% in the previous quarter and 63.5% in the year ago quarter.
Operating margin, operating expenses were substantially lower than planned in the second quarter, mainly due to the decrease in expenses in travel, HR-related expenses and better FX rate. As a result, opex has decreased to a level of $25.1 million versus $26.5 million in the first quarter. And operating margin ended at 20.1%, a record quarter compared with just 15.2% in the previous quarter and 14.1% in the year ago quarter.
Net income growth, increase in sales year-over-year, coupled with lower operating expenses, has driven a meaningful increase in earnings to a level of $10.5 million compared with $7.8 million in the previous quarter and $6.8 million in the year ago quarter. That's an increase of 54.4% year-over-year.
Cash flow was strong. We kept producing cash from operating activities delivering $10.7 million, in line with our plan for the overall year. Headcount, growth in headcount year-over-year for full-time employees was 4.4%. Adding to it growth in outsourced headcount, we grew overall 5.2% year-over-year. Obviously, adding more than 40 position over the year ago quarter clearly demonstrates our confidence in continuous expansion of our business and success in coming years.
Finally, deferred revenues continued to grow and amounted $65.1 million, an increase of 16.7% over second quarter 2019. As mentioned on our previous quarter investors call, I'd like to stress again that with revenue growing steadily in past several quarters and deferred revenue is growing in a similar trend all along, our ability to meet the top line target of every new quarter we are stepping in has improved. Hence, the momentum adds [Phonetic] the confidence in achieving the revenue target in coming quarter.
Now to review of the networking business line. Networking business line kept growing 10.5% year-over-year and has reached a level of $51.9 million, accounting now to 97% of our business in second quarter 2020. With networking being the core of our business, it is important to note that in the first quarter of this year, networking business grew 12% over the first quarter in 2019. And so, on first half revenue -- our first half revenue in 2020 compared to the first half revenue in 2019, overall networking business is growing nicely. It is basically growing 11%. At this stage, I believe that we -- anybody wants to monitor the progress of the company, it makes sense, put side, the technology line and I think we should focus from now on, on networking, which is 97% of the business.
Now, the networking business comprises of two key business lines, UC-SIP and gateways. The UC-SIP business line grew nicely in the quarter versus a decline in our gateway business. UC-SIP business line grew substantially well above 20% in second quarter 2020 and provides now to close to 70% of our business revenue in the quarter. Key to this growth was substantially increase year-over-year sales in OVOC and MSBR product lines. Revenue grew also in our central network management software business line and our advanced routing management solutions. The IP Phone business line remained about flat, compared with the revenue level of the year ago quarter. We attribute this less favorable performance to the [Indecipherable] new normal, which is practically hurting sales of on-prem devices, a trend, which we believe will persist in the near future as habits of organization will become more hybrid and will basically share between on-prem presence and remote work practice in the new emerging digital workplace.
Noteworthy is the fact that revenue in the UC business line grew substantially above what we used to know in previous year of 15% to 20%; meaning that, that large business line and bear in mind, we did last year about $110 million. We target this year to do between $135 million and $140 million. This is in line that carries a gross margin of close to 70% and grows well above 20%. All-in-all, I think that is the key business line of the company. This is where we invest our resources, efforts and energy, and I believe that continuing that momentum will bring the company substantially further in the future. So, please bear in mind that gross margin for this business line increase and now that it is close to 70%. This has provided definitely for the overall company growth of the gross margin to 66.9%. And this is mainly due to the increased sales of software products and related services and the transition to cloud communications.
Now to gateways, in the gateway business, we saw a second quarter in a row of declining revenue. Gateway business line revenue declined more than 15% compared to the year ago quarter. The gateway business line now provides for less than 30% of the second quarter revenue and carries a gross margin of close to 70%. The decline is mainly related to products -- to the products components, which declined above 20% year-over-year. Decline of gateways services was milder at less than 15%.
Now to the Microsoft ecosystem, all-in-all, the business in the Microsoft ecosystem was good. Growth in revenues was close to 20%, just on the heels of the first quarter. In terms of highlights of our performance in Microsoft ecosystem, we saw very strong uptake in Teams' opportunities closure and a very strong growth in new opportunities created. On the other end, we've seen meaningful decline in the Skype for Business-related revenues. I'll refer to more numbers in sequel. Also, slowdown in IP Phone sales due to the setup, new practice of organization, this is the result of the pandemic and the move to work-from-home, and we believe that as I've mentioned before, we believe that trend will persist.
All-in-all, Microsoft continued to report growth and demand for its cloud services and Teams. To quote certain data points on that, according to Microsoft Investor Call of last week, they've stated that 69 organizations now have -- that have more than 100,000 users have moved to US Team; also over 1,800 organization, which have more than 10,000 users, have been moved to US Team. So all that tells you that on the enterprise level -- on the large enterprise companies, Microsoft Teams is a winner, and this is where we sell. So that gives part of the explanation to why we are that successful in that range.
I will give you more data points. There was survey done between the middle of February and June and basically, the survey was about to check the market share of the different team collaboration application. Basically, it shows that in that environment, Microsoft Teams grew from 11.4% to 34.3%. This was an increase of 300%. On the contrary, Skype for Business declined, and that we will explain later on what we also see in our revenues, it has declined from 75% to 44%. Also successful in that period was Zoom growing 127%; Webex -- Cisco Webex was less successful growing about 50% and then, Slack showed 33% growth. All-in-all, Teams stands at the top of the table with more than 300% growth.
On other fronts, we are early few wins in the AudioCodes Live initiative we announced in March 2020. This is primarily about supplying professional services to the Microsoft Teams environment. Also, we keep investing in advance networking solution for Microsoft Teams in order to allow faster growth of Teams users. We anticipate greater support from Microsoft field sales in the new fiscal year for Microsoft in pushing for an elevated use of voice services as it related to Teams, we believe that should be a positive catalyst, etc., for efforts in coming year.
Now to some early dramatic development in Microsoft revenues in the quarter, you all remember that we reported that we have sold more than $80 million of products and services in 2019. That was primarily attributed about, I would say, 99% of Skype for Business; only about 10% to Teams. What we saw in the second quarter is a complete revolution. Skype for Business came down dramatically. Teams grew up dramatically. Skype for Business was down 28% from second quarter a year ago and 20% down from the first quarter. So 20% decline in the first quarter. However, Teams grew more than 336% year-over-year, and that basically tells you -- then almost doubled quarter-to-quarter. So that tells you that growth of Teams have surpassed the decline of Skype for Business and now they notice we have managed to show growing Microsoft sales, it means that we have -- we are doing the transition from Skype for Business teams in a very determining assured way.
On another front, I mean, each quarter -- we measure each quarter by two key KPIs, one which is just reported, the closure of opportunities and sales level. But the other one is really not less important and relates to the future, and that is the amount of new opportunities created in that quarter. So with regard to creation of new opportunities in the Microsoft space, I would like to know that while we saw a dramatic decline in new Skype for Business opportunities, just like in the revenue side of the business, we saw Teams-related opportunities doubling in creation year-over-year. To give you some sense for it, Skype for Business new created opportunities have declined more than 50% in the core; meaning, less and less new opportunities created every quarter. On the other hand, Teams is growing substantially, almost double in terms of number of opportunities -- amount of opportunities in financial extent [Phonetic] over the year ago quarter.
Now, let me bring you -- get you some -- three examples, two important projects we have done in the second quarter. I'll talk first about one of the largest food manufacturing companies in the world in North America. They employ 150,000 employees. They are AudioCodes customer for the past seven years. And they have deployed Skype for Business with our products, be it gateways, session border controllers, management software, recording software, etc. Our overall revenue was down to date, exceeds many millions of dollars. And recently -- I'm glad to say that recently, they said rolling out to Teams.
For Teams, we have secured in the second quarter a $0.5 million deal for session border control for direct routes. This is delivered through a partnership with another big value-added reseller, and we sell this as a service -- a managed service. Additionally, we've secured 700,000 support renewal contract with their current Skype for Business solution. Another example is a Fortune 500 global manufacturing market of packaging products. We're talking about thousands of SIPs using Teams' fully managed service. It's a five years contract. In second quarter, we have secured more than $0.5 million in professional services. Third example is a giant Brazilian bank, and this is a customer of ours for many years now using our gear in Genesys contact center environment. This is by the way shows you AudioCodes' strong position in the enterprise where we are able to provide solution and equipment not only for UCaaS, but also for the contact center. So, they started to roll out Teams with AudioCodes using our SBC routing manager and One Voice Operations Center to help them build the foundation of Teams voice network. Again, it's a $0.5 million contract in the second quarter.
Last, let me mention a large pharma enterprise with several -- 10,000 employees around the world. We have a long-standing relationship that evolved their digital transformation from legacy IP-PBX, just Skype for Business and now ultimately, moving to Microsoft Teams. To date, we have generated about $3 million with this account turning session border controllers, gateways, One Voice Operations Center and more services. In this quarter, we have secured the virtual SBC project with them. We're basically moving with them to the next stage in Teams.
Now, let me move over to the SBC business line. Glad to say that 2020 is a very strong year for the line. We ended 2019 with more than $60 million in revenues. We now anticipate that in 2020, we will reach above $80 million. So all-in-all, we predict for more than 30% growth on SBC. We are clear leader in SBC. On June 24, we issued a press release where Omdia has released a report that says that AudioCodes has experienced a 24% year-over-year growth in SBC revenues in first quarter of 2020, more than any of the other vendors covered in the report during the quarter. AudioCodes is ranked second among enterprise SBC vendors in the report with 17% overall revenue market share. So all-in-all, very strong position in the SBC market.
As we all know, the key application of SBC is around SIP trunking and also using transition to All-IP. We've seen dramatic growth in Teams direct route using our SBC. We now see few more new applications, namely if you think about WebRTC that will be used for work-from-home, if you think about a new voice network defined, if you think about virtualizing cloud migration, if you think about the telephony engagement for virtual agents. So all-in-all, SBC is a very key network element in every new solution that's being deployed, and we know that we are sitting among the leaders in that market.
In terms of the quarter specifically, this was a record quarter. Revenues reached well above $20 million. We basically saw an increase of more than 10% quarter-over-quarter and more than 50% year-over-year. The business line carries a very high gross margin, above 85%. We've seen good activity both in the service provider SBC, CPE and in the enterprise. In terms of a geo split, 36% of revenues were in North America; 38% in Western Europe, Russia and Asia Pacific and CALA. We have seen strong booking, almost 50% year-over-year. We also saw an increase in new created opportunities. So all-in-all, a very strong established line.
One key new development that's important, then I keep talking about our transition to being a communication software company is that we try to increase the software content in every business line that we involve in. So just looking at the SBC line, when we started the year ago with software being providing about 26.8% of the overall SBC line, now a year after that, the software SBC accounts to almost 40%. So a very strong increase above 50% in the software content of Session Border Controllers. Obviously, that relates to more deployments of virtualized SBC in public cloud than in private data centers.
To give you two examples for wins, just as we did with Microsoft, so we won a very lucrative contracting and interconnect SBC with a very world-known leading communication vendor in the space. Basically, they were looking to expand service and operation in specific countries in Asia Pacific and CALA, and there was a need for a high-capacity resilient SBC platform that will meet certain regulatory requirements. We were selected out of basically seven SBC containers, all of the known names in the industry. Thanks to our flexible SBC capabilities, alongside the One Voice Operations Center lifecycle management suite and primarily due to real-time voice quality monitoring. This win joins previous session border controllers and WebRTC wins with leading contact centers and service providers in North America and Europe. It demonstrated a real life constraint in need for faster deployment cycles, great business opportunity for high scale SBC with pure-play cloud providers as they scale up their service.
In another example, we're talking about world-leading e-commerce vendor due to the COVID-19 needs and due to regulatory requirements in the country. The company now has to move more than 10,000 of its customer support agents to work-from-home. This customer is already a multi-million-dollar account for AudioCodes, which has purchased and deployed VoIP gateways and session border controllers. Its opportunity is around our integrated WebRTC gateway that is a key differentiator versus main session border controllers competition. The customer like other mega enterprise has very strong internal development teams and developed their own WebRTC clients based on their own WebRTC and client SDK. The WebRTC gateway is needed for termination of the calls.
I'll talk a bit also on the work-from-home opportunities. As mentioned in our previous call, we see a very fast ramp-up and the need to provide good quality of service solution for contact center agents moving to work-from-home. And thus, I can tell you that in previous month in the second quarter, we have seen an uptick in the number of new opportunities created, and we work to come up with a solution that will far exceed the capabilities of any other work-from-home quality monitoring and delivery solution.
I'll mention more -- one very promising product for us. Let me talk about the Voice.AI Gateway. We're talking here about a session border-related development, which adds on top of it the various components and allows basically to connect existing chatbots to voice and telephony channels. Now, it's obvious that with COVID-19 pandemic, the need for chatbots is increasing. We are all locked into situation where we need to approach certain organizations and/or suppliers in our ability to -- since we're all calling them by phone, we have two key promises: A) not all of us are accustomed to using chatbots, so that's a problem. On the other hand, when you have too many phone calls coming into a contact center, A) you need to use more agents and then, you get substantially longer wait times. So we have developed the Voice.AI Gateway to allow connection of voice calls to chatbots and thus, we can A) improve substantially the response time and B) also provide a lot of saving for the cost of those agents. That product is already in use with several customers.
I just mentioned that so far, we have more 50 opportunities created; out of which, 20 were created in the second quarter. We have more than 10 opportunities that were closed one. We have few already in production, less than 10. Partners' picture is very encouraging. There is no such comparable capability these days at the level and performance we provide. And so, we are able to get to work with many chat developers in both framework vendors in the space and also with some of the big names you all know from the public network. So all-in-all, a very successful product, very successful activity.
I'll also mention, a quarter ago, we announced collaboration with Google on the One-Click program, which is meant to allow to connect and provide phone numbers in the US and UK to chat developers. I'm happy to say that there's been a lot of interest in that new service. We had more than 100 people signing in. We have more than 10 active accounts right now. And we believe that is a great lead generation tool for us for the growing chatbot world.
Regarding services, I already mentioned, revenues just touch another angle, which is bookings. So in the second quarter, we grew very nicely in bookings, 6.3% compared to the second quarter year ago. Very impressive is the growth of more than 40% professional services year-over-year. So all-in-all, a very active quarters in terms of professional services.
Finally, I'll come to our guidance. So in terms of revenues, we estimate -- Niran mentioned already, we reiterate our guidance from the beginning of the year and see no reason to change it. We feel fully confident in achieving it. As he mentioned, the current range is targeting between $214 million to $222 million. As regards to earnings, in second quarter '20, we were able to meaningfully beat original plan and the analyst consensus. For the rest of 2020, we believe that we will see similar patterns of revenue and operating expenses and thus, we are confident in our ability to continue to grow earnings. As a result, we now update our earnings guidance and increasing earnings range from $1.09 to [Phonetic] $1.15 to $1.18 to $1.24.
And with that, I've completed my introduction for the quarter. And we'll now turn the call into Q&A. Operator?
Questions and Answers:
Operator
Thank you. [Operator Instructions] Thank you. And our first question comes from the line of Tal Liani with Bank of America. Please proceed with your questions.
Tal Liani -- Bank of America -- Analyst
Hey, guys. Thank you very much for the comprehensive overview of the quarter. I want to ask you -- I want to go back to basics and understand, first of all, within Microsoft. What's the current use of voice in unified communication, and what are the efforts done? What's the outlook for increased use of voice, because I understand that it's about unified communication and about Microsoft meetings, but it's more about the use of voice within the platform? So that's number one? And number two, can you talk about your efforts with other players other than Microsoft meetings, and what can you do for other players? Thanks.
Brett Maas -- Managing Partner
Shabtai?
Shabtai Adlersberg -- President and Chief Executive Officer
Okay. Yeah. I'm sorry. I was in mute. Thank you, Tal. Thank you. Regarding voice, voice is definitely probably one of the most important ingredients in unified communications. Put it side with chats [Technical Issues] if you run statistics, statistics says that voice is the most preferred medium of communication. Now, Teams provide the voice capability for on-net internally. There's no need for voices -- for voice services outside it. But, once you want to get a dial tone, once you want to talk with third-party organization, you want to dial them or get a call, you need to add voice services. That is on the connectivity side, very simple functionality, sometimes very complex in terms of implementation, but essential to having a full, comprehensive, unified communication solution.
However, now think about the new world that's emerging, and that's the world that knows to process the content, knows to take voice content and produce results from it. So if we were talking about virtual agents, then if you want to save costs, if you want to provide a service substantially faster than waiting on the line for an agent, you have today a technology that takes the voice part of that and basically can apply speech-to-text, natural language understanding, machine learning, few more technologies that will now take advantage of the content itself. So, connectivity is key for connect to other organization. Content processing is key. So voice is primarily a key technology within every communication solution, and that's the approach we take.
Regarding your question as to working with that organization, we definitely try to do that. We have partners. I can name a few working for many years now with companies like 8x8 and RingCentral and Vonage. We announced certification for Zoom. We have growing opportunities with Zoom in 2020. We have announced partnership with AWS Chime. So all-in-all, we're very active. We work with some legacy names like Alcatel. And we work also with companies in the contact center market. We work with Genesys and two more of the leading companies in the contact center market. So all-in-all, we have a broad play, and we try to work with more parties, but at the end of the day, right now, it seems that the majority of our growth and success will reside with Microsoft Teams, which is obviously a very dominant and successful player in the market.
Tal Liani -- Bank of America -- Analyst
Great. Shabtai, if I can just have a follow-up on your first answer. So when you talk about analytics, can you discuss the reception you're seeing from clients? Are there -- what's the competition there? I'm sure that there are other solutions that can ride on top of any voice company and provide the analytics. But what's the benefit of customers to go with you versus others? And what's the reception that you're seeing from clients?
Shabtai Adlersberg -- President and Chief Executive Officer
Right. A) we enjoy the fact that we are a very known brand and established vendor and supplier in the enterprise world. So we have access to a lot of the large enterprises I have mentioned before. So selling up in an existing customer usually is easier. Second, the company has early established, more than 20 years public, many years in the business, very advanced sophisticated telephony capability, quite an established organization with no functionalities. We have found ourselves several times competing with new start-ups. At the end of the day, our scale, our brands, our capabilities, I'm able to throw resources into a project because it is important to me. We find ourselves preferable with customers, due to the fact that we are a very established and strong vendor.
So all-in-all, one more data point is never discussing those cases is the fact that contrary to the products when you're in the past, take a router, take a firewall, take anything that is a standard product, the winner takes it all. So if Cisco was leaving the router market, it was a very tough for other companies to plan, simply because they had reached to the overall market.
When you're talking about cognitive services, when you're talking about speech-to-text and text-to-speech, you're talking about languages. And here, the picture is completely different. So that allows us to penetrate several markets in parallel and basically will allow us to be much more successful because we will have the scale. If AudioCodes can sell to, let's say, the US, Germany, UK, Japan and Australia, you bet that our ability to invest resources and get to results will be substantially better than an Australian-based start-up that will be maybe successful in Australia, but will find it hard to expand being a smaller platform. So all-in-all, I think we're sitting in a very comfortable situation.

Got it. Shabtai, I'm just going to squeeze in one little -- one small additional question and that's for Niran. Your revenues were roughly in line for the quarter, roughly in line with expectations, but your gross margins were almost 200 basis points above. And your operating margin was a lot more, was almost 400 basis points above. So, first, what drives this great margin performance? And second, what's the sustainability? What's the outlook for the next few quarters? What are the puts and takes for margins?
Niran Baruch -- Chief Financial Officer
Okay. So actually, what drives the gross margin to 66.9% was mainly the increase in software revenue as Shabtai mentioned in the call, more professional services and all-in-all, a product mix was benefit. This quarter, we had more revenues from SBC, which is in high gross margin. And less revenue is related to phones, which is in low gross margin. We believe it's sustainable for the coming quarters and even may improve because we are selling more and more software revenues.

Our next question is from the line of Samad Samana with Jefferies. Please proceed with your questions.
Samad Samana -- Jefferies -- Analyst
Hi, good morning. Thank you for taking my questions. Maybe one to start with on -- a follow-up on Teams, it's clearly outstanding. How much of that was Skype for Business customers migrating to Teams versus maybe organic net new Teams' customers using voice? And then, I have a follow-up question. Hello?
Shabtai Adlersberg -- President and Chief Executive Officer
Sorry to disappoint you Samad on that. I really do not have the data with me now. I will look into it, and I will provide the answer. But we've seen -- I can tell you that we are seeing definitely a mix between new customer, and some of the customers already use -- as I mentioned in some of the examples that you have already using Skype for Business and moving. But I don't have the actual division with me right now.
Samad Samana -- Jefferies -- Analyst
Okay. That's helpful. And then, maybe just as a follow-up to that. If you think about generally the customers that are adding voice to Teams through AudioCodes, any characteristics in terms of maybe the average size of the customer, or is it usually a full end-to-end deployment, or is it a phased roll-out? How should we think about maybe the ramp that individual customers rolling out voice into Teams?
Shabtai Adlersberg -- President and Chief Executive Officer
Okay. That's actually a very interesting question. I'll tell you why, because in the past, when Microsoft was selling mainly Skype for Business, large companies always took the time to do a pilot, deployed it with several branch offices and then, continue the deployment every quarter in coming years. I think the situation right now with Teams is completely different. I think these days, organizations are moving out of necessity. Nobody has the time to wait for a prolonged deployment. So -- and because actually there's no deployment, I mean, we're not talking about deploying Microsoft servers on-prem. We're talking about using a cloud service. So actually, you can think about companies going online with Teams all across the company unless, of course they want to first try it with a smaller group. So that's regarding that. I'm sorry, your first question was, Samad?
Samad Samana -- Jefferies -- Analyst
No, you got them both and just to get that roll-out cadence. And maybe just one final financial question. Clearly, the earnings was a solid performance this quarter. How should we think about maybe the investment philosophy for the back half of the year on expenses since -- if I heard the guidance correctly, there is -- the guidance was just reiterated. So is the upside planning on being on reinvested or how should we think about opex trends maybe for the rest of 2020?
Shabtai Adlersberg -- President and Chief Executive Officer
Okay. So opex indeed decreased from a level of $26.5 million in the first quarter to $25 million in the second quarter. It was mainly related to less expenses, related to travel and to HR-related expenses. I can tell you that our planning for the second half of 2020 is to be -- to still saving in these major expenses, travel and HR-related. Moreover, we have a better FX rate, Israeli shekel against the dollar and as such, we believe the opex -- it will be increased, but not too much compared to the second quarter of 2020.
Samad Samana -- Jefferies -- Analyst
Okay. I appreciate you taking my questions. And thanks again for the time. Have a good day.
Shabtai Adlersberg -- President and Chief Executive Officer
Thank you.

Thank you. [Operator Instructions] The next question is from the line of Rich Valera with Needham and Company.
Richard Valera -- Needham & Company -- Analyst
Thank you. Shabtai, you've noted the conflicting dynamics in the Microsoft business with Skype for Business declining and Teams growing quite rapidly. How do you think that nets out for you kind of for the year from a year outlook perspective for Microsoft? And then, taking that a level higher, UC-SIP sounded like it's all very good growth overall. So how do you think about kind of UC-SIP outlook for the year? Do you think that's kind of a 20% or better growth business overall for the year? Thank you.
Shabtai Adlersberg -- President and Chief Executive Officer
Thank you, Rich. Yeah, that is indeed a very interesting question. As I've mentioned before, take our $20 million plus revenue for the second quarter, I'll give you a more -- one more data point that Teams and Skype for Business who are basically around the same level, give or take $1 million. Now, the real question is how fast Skype for Business declines, purchase orders, or Skype for Business related equipment decline versus growth in Team. We think a very strong pickup in Teams. Actually, as we speak, this is now July 28. Already, the current ramp-up in the third quarter is substantially better than what we've seen in April. So, I'm confident that at least based on data we have in hand right now, that growth in Teams will more than outgrow to declining Skype for Business. Also let's bear in mind that every time a business line is dropping, the majority of the drop occurs in the initial phase and then, it -- basically it's waited out. So all-in-all, we're pretty confident in our ability to keep growing the Microsoft revenues for the rest of the year. And we believe we will see continued growth next year.
Also, I'll mention that we all -- we try always to increase the new products and new services we offer in that environment. So in many ways, our offering for Skype for Business was kind of altered more than a year or two years ago. And on the other hand, we have, as I've mentioned, more investment in new offering, new opportunities for Team. So all-in-all, we believe the Teams will be fully successful.
Richard Valera -- Needham & Company -- Analyst
Got it. Just one more if I could on the service revenue, which I guess, was a little light from a growth perspective this quarter, but it has shown some historical lumpiness. How should we think about that going forward? Was that just kind of lumpiness, and should we expect that the kind of resume more of its historical growth trajectory?
Shabtai Adlersberg -- President and Chief Executive Officer
Yes, definitely. I mean, services basically has two components. One is the maintenance contracts, and the other one is professional services. Maintenance contracts, it's already years, five, six years now that growth in a year is usually between 11% to 15%. And we believe we will see the same year. So I mentioned already if you take into account the first half of the year, the growth was 13.2%.
However, there's another component, and this is the professional services. And here, I think the picture is substantially rosier. We are growing substantially. There's much need, by the way, a philosophical point. When people are saying it all time [Phonetic], although they are productive and efficient, when it comes to new large projects that has to occur within a company, it's always substantially more difficult to put them to work and complete them when you have people distributed all around the place. So you can assume that the need or desire to move to use more services from a party that can provide them, you can assume that desire is growing. And therefore, we believe that professional services on a global basis will become a much more successful area for deployment. This is what we focus these days.
Richard Valera -- Needham & Company -- Analyst
