Thank you, Brett. Good morning and good afternoon, everybody. I would like to welcome all for our fourth quarter and full-year 2019 conference call. With me this morning is Niran Baruch, Chief Financial Officer and Vice President of Finance of AudioCodes. Niran will start off by presenting a financial overview of the quarter. I will then review the business highlights and summary for the quarter, and then discuss trends and developments in our business and the industry.
We will then turn it into the Q&A session. Niran?
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 fourth quarter were $52.8 million, an increase of 2.7% from the prior quarter, and a 15.3% increase compared to the fourth quarter last year. Full year 2019 revenues increased by 13.7% to $200.3 million. Services revenues for the fourth quarter were $17.5 million, accounting for 32.2% of total revenues. On an annual basis, services revenues increased by 14.7% compared to the previous year.
The amount of deferred revenues as of December 31, 2019 was $62.2 million compared to $49.2 million as of December 31, 2018. Non-paid deferred revenues as of December 31, 2019, at the amount of $19 million was deducted from the trade receivables in the balance sheet.
Revenues by geographical region for the quarter were split as follows. North America, 39%; Central and Latin America, 12%; EMEA, 36%; and Asia-Pacific, 13%. Our top 15 customers in aggregate represented 63% of revenues in the quarter, of which 51% are attributed to our 11 largest distributors.
The variance between GAAP and non-GAAP is of particular importance this quarter because as announced in November 2019, we entered into a Royalty Buyout Agreement with the IIA, the Israel National Authority for Technology and Innovation relating to certain grants we had received.
The contingent net royalty liability to the IIA with respect to this grant at the time of the Royalty Buyout Agreement was approximately $49 million. As part of the Royalty Buyout Agreement, we agreed to pay approximately $32.2 million to the IIA to settle the $49 million debt in full, in three annual installments starting in 2019. The $32.2 million expense is included in the GAAP cost of revenues for the fourth quarter of 2019, and impacts GAAP results for the three months and full year ended December 31, 2019.
Non-GAAP results exclude this expense. In addition, during the fourth quarter of 2019, we recorded a deferred tax asset in the amount of $20.5 million, which represents the approximate amount of net operating losses and temporary tax differences we estimate to be utilized over the next few years. GAAP net income for the fourth quarter and full 2019 year reflect the effect of the tax benefit associated with the certain of this deferred tax asset. Non-GAAP net income excludes this non-cash deferred tax benefit.
With that understanding, let me discuss the results. GAAP gross margin for the quarter inclusive of this $32.2 million expense for the Royalty Buyout was 3.9% compared to 62.6% in Q4 2018. GAAP operating loss for the quarter was $26 million compared to an operating income of $5.1 million in Q4 2018. Full year 2019 GAAP operating loss was $9.6 million; GAAP net loss for the quarter was $8.2 million or $0.28 per share compared to net income of $4.5 million or $0.15 per share in Q4 2018.
Full year 2019 GAAP net income was $4 million or $0.13 per share. As noted above, results for the quarter and full-year were impacted by the $32.2 million expense incurred in connection with the Royalty Buyout Agreement. Pursuant to the Royalty Buyout Agreement, we eliminated all the royalty obligations related to our future revenues with respect to these grants. This will have a positive impact on GAAP gross margin starting in the first quarter of 2020.
Non-GAAP results are as follows. Non-GAAP gross margin for the quarter was 65.1% compared to 63% in Q4 2018. Non-GAAP quarterly operating income was $8.3 million or 15.7% of revenues compared to an operating income of $6.3 million in Q4 2018. Full year 2019 non-GAAP operating income was $28.2 million. Non-GAAP quarterly net income was $8.1 million or $0.26 per share compared to $6.3 million or $0.20 per share in Q4 2018.
Full year 2019 non-GAAP income was $27.8 million or $0.89 per share. Our balance sheet remains strong at the end of December 2019, cash, cash equivalents and bank deposits totaled $71.9 million. Net cash provided by operating activities was $2.4 million during the quarter and $23.2 million for the full year 2019. Both numbers were impacted by the $10.7 million payments made in December 2019, which was the first installment pursuant to the royalty buyout agreement.
Days sales outstanding as of December 31, 2019 were 48 days. In August 2019, we received court approval in Israel to purchase up to an aggregate of $12 million of additional ordinary shares pursuant to our share repurchase program. The court approval also permitted us to declare a dividend of any part of the $12 million during the approved validity period. This court approval will expire on February 3, 2020. As of today, we have used an aggregate of $3.5 million of these authorized amounts to declare cash dividend.
In December 2019, we submitted a new application to the Israeli court requesting approval of an additional repurchase program for $12 million of ordinary shares. The application also requested the court to permit us to declare cash dividends of any part of this amount. A decision on our application is expected during February 2020.
We continue to expect top line revenue growth and operating margin expansion in 2020. We expect revenues in the range of $214 million to $222 million, and non-GAAP diluted earnings per share of $1.08 to $1.12.
I will now turn the call back over to Shabtai.
Shabtai Adlersberg -- President and Chief Executive Officer
Thank you Niran. We are pleased to report record financial results for the fourth quarter and the full year 2019. 2019 has been our best year ever and the fourth year in a row of continued growth in revenues and net income in every single year. And so, when discussing 2019, and looking forward to 2020 and beyond, it's clear that we are now reaping the fruits of success in our eye on investments we have been doing during the past five years, with the very focus on providing more comprehensive and larger scale solution and services to our partners and customers in the unified communication and all-IP markets.
Underlying our success in 2019 is the progress we've made in several key financial indicators which best demonstrates our success since 2015. Let me touch on each of them. Revenue growth. We saw double-digit revenue growth for the second year in a row. We grew 13.7% in 2019. We grew 12.4% in 2018. Margin expansion. Let me talk first on the gross margins. We saw steady progress in improving gross margins from 60% in 2015 to 63.7% in 2019. Planning for 2020, we expect further increase in gross margin. Operational margin improved in more impressive manner. We ended 2019 with operating margin of 14.1% compared to the year-ago margin of 11.7% and compared to just 8.2% in 2017.
For 2020, we target again meaningful increase of operating margin to well above 15%. Net income growth for four years in a row, we are delivering high double-digit net income growth in the range of 30% to 60% in every single year.
In 2019, we delivered 38.9% growth on the heels of delivering 54.9% growth in 2018. Cash flow. We have demonstrated further consistent ability to deliver growing positive operating cash flow results in previous five years, generating $33.9 million in 2019, compared to the $25.6 million in 2018. Out of the funds generated in the fourth quarter of '19, we've paid about $10.7 million to the Israel Innovation Authority as part of the Royalty Buyout Agreement signed in November in 2019.
Finally, deferred revenues, we grew more than 25% in 2019 to a level of $62.2 million by the end of 2019 versus just $49.2 million in the fourth quarter of 2018. When we analyze what has driven the success in 2019, it is clear that the improved financial performance was achieved mainly due to the strong trend of PSTN transition to all-IP in North America and in about three or four countries in Western Europe with a handful of major Tier 1 service providers.
We expect this migration trend to IP to continue in coming years and we plan to engage with more service providers in countries, which have yet to start at all transforming their networks and services to businesses to all-IP in the coming decade. We're talking about five years to 10 years going forward. But on a more general level, if I have to highlight the key fundamental reasons for the success we enjoy, I'll say on a general level that the strength of our business is primarily related to the very strong and healthy markets we serve, and obviously our execution capability.
I have talked so far about the all-IP market. A bigger market that keeps growing for the past 10 years and we should keep growing for the next foreseeable future is the unified communication and unified communication-as-a-service market. This market exhibits compound annual growth rate of about 18% for several years now and with whole penetration only at about 25% in North America and only 7% globally, this market offer us a lot of room for expansion and growth for a voice infrastructure vendor like us. When you add to the mix, the leadership position we develop and the strong ties with our partners the picture gets rosier.
Same growth trends apply to global digital transformation trends of businesses, gearing toward a digital workplace. And similarly such opportunity exist in the process of contact center migrating to the cloud into a SaaS model.
So as long as we keep executing as we did in 2019 and in previous years, we should see positive results in coming years. On top of this and in order to keep the business momentum and allow further expansion of our business in the future, we are investing substantial efforts and resources in new growth engine such as the Voice.ai business announced two years ago and the new evolving meeting space market.
Now to the business lines. Key to the success in 2019 is the consistent progress in our networking business, which grew 17.7% year-over-year to $191.7 million accounting now to 96% of your overall business in 2019. The networking business comprises of two key business lines, the UC-SIP business line and the Gateway business line. The UC-SIP business line grew above 20% in first quarter '19 and full year 2019, and provides now to about 55% of our business about $110 million in 2019.
While investments have stabilized in size in this business line over the past several years, revenues continue to grow with about 15% to 20% annually. As a result, the business line becomes quite profitable. It first achieved profitability in 2018 and now it has more than doubled in 2019. As such, we now enjoy growing profit margins, say results of the operation of leverage.
At this stage, we do not anticipate a change in this 15% to 20% annual growth in coming years for this business line. Quite important to note is that the steady annual increase of sales of more softer products, and growing services in the UC-SIP business line, we experienced substantial improvement in the gross margin of this business line. And please remember, at this stage this is $110 million line, 55% of our revenue in 2019.
Now let's talk a bit about our Gateway business, parallel to the growth in UC-SIP, we enjoyed in 2019, a strong year in our Gateway business, which grew above 10% compared to 2018 and reached a level of about $70 million. As mentioned before, this is substantially due to the ongoing strength in the multi-year continued migration of service providers PSTN networks to all-IP. Global services also demonstrated very solid growth and strength. I'll touch on that later on.
Providing a quick snapshot into the first quarter of 2020. I'm glad to know that at this stage the trend in our business continues in January, the first month of the first quarter of 2020. Touching on the highlights of sales in the fourth quarter in 2019, generally sales performed very well to and above the targets we set for them. So very good performance, remarkable performance primarily in North America, in the DACH region, which is Germany, Switzerland and Austria, in the UK, in CALA, Russia and Asia Pacific.
On an annual level, those were mainly in North America, the DACH region and South Europe, that provided most of the revenue. To mention some of the notable deals in the quarter, we won a huge multimillion project in CALA, we are talking about project managed by Telefonica, and which provide a solution to a large company, I'll refer to more details about that later.
Also, on the business services side, we had very large purchase order with the North American service provider that's a buying customer for several years now. Same since, I already mentioned the name Deutsche Telekom, Deutsche Telekom was a very strong for us overall 2019 and also in the quarter, a few hundreds of thousands of dollars. Touching on the contact center space, I'll note two deals, one in Brazil, one in Canada both deals relied on using our sessions border controls and gateways with Genesys and others.
To give you some examples to our customer wins. Let me put more color and share a few examples of customer wins and expansions that we have secured part of this quarter. Outlining several of the examples, you can get a sense for how is our business, our enterprise business, how it is evolving with large opportunities in large corporations, and how our strategy is aligned and growing with cloud adoption.
Let me first start, touch on that South America multi-million project. Last year, sorry last quarter, we presented a multi-million dollar win in the healthcare space in the US. This quarter, we were awarded an even bigger multi-million Microsoft Teams deal at the Latin American government agency. This agency, which is a part of the local Ministry of Labor oversees a large national chain of schools for developing employees' skills. In this bid, we have positioned our entire portfolio of products and services including devices, networking, management tools and implementation services.
We are proud to win such deals as they demonstrate again that our strategy of single stop shop solutions holds tremendous value for the customers and end users. This deal validates our ability to offer a networking solution for over 100 branches together with over 10,000 of IP phones. It clearly sets us apart from competition and our ability to balance and offer a broad value proposition to the customer.
Second, and staying on the Microsoft Teams program and exploring the dynamics of markets for very large enterprises, we started to rollout a Teams deployment at one of the world largest consumer goods companies. This company was referred to us by Microsoft at one of their Internet shows. This was because we were highlighted at that show as the vendor empowering the rollout of hundreds of thousands of Skype for Business seats across four multinational enterprises.
This large consumer goods company has thoroughly vetted the Microsoft solution, and it's just getting started with their global rollout. At first phase, we are providing our session border controllers, and professional services. This deal is representative of many such large enterprises globally that we work with on their Microsoft Teams' journey.
Third and last, a very large project in the US related to our all-IP migration solution for service provider, a very important multi-million win came from a Tier 1 service provider in the US where we were engaged to provide gear and services in a multi-million dollar deals, combining SD-WAN and UC services to a nationwide healthcare company.
In this deal, our unique offering of Universal CPE combining Wireless and Ethernet access with voice functionality was chosen as the SD-WAN platform in order to reduce the number of several CPUs down to only one product. This product combined with our gateways from centralized management and professional services were the deciding factor that got us this sizable deal.
Now let me touch on Microsoft. Revenue was above 40% of the quarter revenue. In terms of growth, we saw 16% growth above the year-ago quarter. On an annual level, revenue in the Microsoft ecosystem grew about 12% to over $80 million in 2019. Key in the quarter was seemingly better environment for Microsoft Teams Voice. While as we've planned during the first three quarters of 2019, we saw more large end users embracing Teams in the fourth quarter of 2019, a trend we continue to see in January 2020. Also, some customers are continuing in parallel with Skype for Business and Teams.
For Microsoft announcement, we all know that Teams daily active users is growing rapidly in 2019, and so we expect the side-by-side with this dramatic growth in users -- number of users and with the expected completion of gaps on the voice side in Teams, which are expected in this first half of 2020, we should see better overall market in 2020. Gradual progress in developing market awareness to our meeting solution, Rx Suite of Conferencing Devices and Dolby partnership is another positive development in the quarter, and we all look for 2020 to be the first year of our greater penetration in the conferencing space with our devices and solutions.
I'd like to mention also on our session border controllers line, which is the leading and most promising line at this stage within the UC-SIP business line. In the fourth quarter, revenue grew 18.4% year-over-year, looking on overall 2019, we grew more than 20%. We also saw very strong booking. Booking grew in the first quarter by 28%. This business line is characterized by extremely high gross margin that's above 85%, growing in comparison to the previous quarters. This is mainly to the fact that a quarter for our sales of product is now in software. So, we are being deployed generally substantially more in cloud, in software solution, in virtualized version, in data centers, all-in-all, very successful fast growing and high profit margin line.
On terms of geo split, we saw nice use, both almost equal between North America and Western Europe. Also saw some 10% in Asia Pacific and less than that in CALA. To mention the type of few customers that we serve in that business line. So we had one very large North American service provider using our SBC. We sold SBC for more than $1.5 million. We sold two large banks. One in Brazil. One in Russia, consuming our session border controllers for -- we're about to see in our solution for software device -- software-defined voice networks.
Also, in the Asia Pacific large service provider is using our session border controllers within Azure as a hosted solution for Teams direct route SBC. All-in-all very successful quarter for SBC business line. Last, let me touch on global services. In the press release, you saw the recognition side of the business. Let me talk about the booking side of the business. So, on a quarterly basis, we saw the following, we saw an increase of 26.2% in the fourth quarter for total services.
We've seen 19.2% growth in maintenance contracts, but we have seen more than 60% growth in professional services, all that in the fourth quarter. When we go to the annual level and talking about what has changed. So, overall booking of services reached above $70 million in the year. We grew about 19% on an overall services level, close to 18% on the maintenance contracts, 24% on the professional services. So, all-in-all quite successful and rapid growth here. Substantially, we saw -- to give some color on that we saw substantial growth in North America professional services mainly the team there is doing a fantastic job.
We keep winning new managed services contracts mainly in desire throughout SBC area. Also, we see growing a number of requests to deploy and manage the Teams Voice on the Office 365 side. Now to our guidance for 2020. First, a general comment. We have not factored in any possible impact of the potential economic developments in 2020 as a result of the Corona virus. It is simply too early for that for us.
Now let me touch on revenue and earnings. Revenue, based on current plans and data we have, we guide for another year of growth with revenue range set for $215 million to $222 million. The mid-range guidance is set at about $218 million and that represents a growth of about 9% compared to 2019. This is pretty much in line with the 10% growth we guided for year ago for 2019.
Now let me touch on earnings. Before I present our guidance for the year, I'd like to touch on a key factor affecting it for us as a company at core and based mostly in Israel. I'm talking about the much different US dollar versus the new Israeli shekel conversion rate environment, which is now expected for 2020 versus what we had in 2019.
Based on current rates for budget and planning purposes, we assume a rate of ILS3.45. In 2019, the average conversion rate has been about ILS3.57. So we are talking about an increase of about 3.4% regarding all expenses nominated in new Israeli shekel, which are about ILS45 million a year, translating to an impact of about $1.6 million or $0.05 impact on our bottom-line compared to 2019.
Now to the guidance. As a result of that, we now guide for continuing growth in the earnings of more than 20% in 2020, and we are setting the range to $1.08 to $1.12.
With that, I've basically completed my introduction for this session. Thank you very much. Operator, would you take us to the Q&A session.
Questions and Answers:
Operator
Thank you. [Operator Instructions] Our first question comes from the line of Rich Valera with Needham & Company. Please proceed with your question.
Rich Valera -- Needham and Company -- Analyst
Thank you. I'd like to open with a question on the Microsoft Business. Looks like you saw a nice pickup in the fourth quarter, the Microsoft businesses, I guess, Teams is starting to gain some momentum. Can you talk about what is still in the pipeline for Teams in terms of features that you see that could help further accelerate Teams? And how you're thinking about the overall Microsoft Business in 2020 versus the 12% growth that you saw in 2019? Thanks.
Shabtai Adlersberg -- President and Chief Executive Officer
Right. Thank you, Rich. First, you know, we know that there are several features missing for the voice implementation within Teams. From our ongoing discussion with Microsoft, we know that the plan is now to complete them in the first half of this year. So all-in-all, we know that much will start happening in the second half.
Second, as I have mentioned before in the beginning of 2019, we've seen lot of potential end users, large corporation sitting on the fence. People were hesitant. The transition from Skype for Business to Teams has just started. Teams was not complete yet. And there was much delay. That gives some explanation to why we grew only 12% in 2019 versus more than 30% in 2018.
Now, we do expect and we've seen that that's where we have a much more comprehensive portfolio and you can apply that to more phones that will be introduced during 2020. We can talk about the conferencing devices that we just -- end of the year, we just sent the first few 100 devices for evaluation by customers. So, a much more complete portfolio in 2020. Also we are increasing the set of services we offer. And as I've mentioned or maybe it was not emphasized enough, we now start to deal substantially with more deployments where we not only deliver the products, but also provide services and in several cases, lately managed services, meaning large companies, a few hundreds and sometimes thousands of companies will rely on AudioCodes to provide their ongoing daily Microsoft Teams operation.
So all-in-all, we're very optimistic regarding that could be a definite change in 2020 compared to 2019 and we will just have to wait and see for the next two quarters to see that indeed happening.
Rich Valera -- Needham and Company -- Analyst
Great. And I wanted to move on to Voice.ai. This has been an area of significant investment for you. We just hoping you get a little -- put a little more color on kind of one, how much revenue contribution you've actually seen from that to-date? How much investment you've put into that on an annual basis? And how you're thinking about the potential growth of that business over the next couple of years?
Shabtai Adlersberg -- President and Chief Executive Officer
Right. So, first, let me put an overall framework on this. We have at this stage about 60 people employed in the Voice.ai business, which we officially announced two years ago. The business is still growing. Last year, we did above $2 million of sales in that line. We do expect an increase of at least 50% to 100% this year in 2020. The investment basically, we have two parts of the business. One is the recording services, the other one is more, the speech recognition and NLP services. So, in the recording side of the business, we have a compliance recording application, which is growing and starts to grow further and now the Teams is a new market for them.
We've also discussed few months ago, launching Meeting Insights, which will allow us to record the interactions in the office. We're talking about meetings, which will be recorded, then we'll later on allow management and other people to analyze them and look for facts, automated -- automated action item taking, identify speakers, you'll have a great repository of voice interaction in the office that are searchable, pretty much compared to when you go for your outlook to look for a mail or a data message that was sent.
Then we substantially improved our stack of technologies in the voice recognition area. We have developed a very strong deep neural network solution that's now deployed in two languages. At this stage, it's Hebrew and German. Also going to be deployed shortly with US English. NLP has been developed. We've been working substantially on opportunities in the customer engagement area, virtual assistant and we definitely start to pick up in the number of projects that we performed. So all-in-all, we're very -- while investing a lot, by the way, the expense on that business in 2019 was about $4.5 million, meaning that, it's quite a large investment, but we do feel that within the next three years this operation will become fully successful growing fast.
I'll mention also that, we did a very unique development that we call Voice.ai gateway and that technology allows you to voice-enabled chatbots and with chatbots and both being used increasingly in the enterprise and in other places the ability to add voice channels to it both in the recognition side and then in the synthesizing side is a great solution. This solution is already being implemented with two or three large corporations. There are five or more in the pipeline. So all-in-all very encouraged by the progress we're making on the Voice.ai.
Rich Valera -- Needham and Company -- Analyst
Got it, thank you for that. And then, I wanted to just talk about your -- the seasonality of your business into the first quarter. Sounds like it's -- you are continuing to see pretty good momentum. In the last couple of years, you've actually seen a modest seasonal uptick Q4 to Q1. So just wondering how we should think about from a modeling perspective that the Q1 revenue relative to the Q4 revenue?
Shabtai Adlersberg -- President and Chief Executive Officer
Yeah, yeah. I've learned in the past not to rely on miracles, enjoy them. So, for planning purposes I usually plan on a down quarter that will be roughly around 2%. But you've mentioned, rightly, yes, in past years, we've been able to beat that and actually grow. So, we try to stay modest. I think we saw that in our guidance for the revenues and profits and we'll start a new year just as we did in 2019.
Rich Valera -- Needham and Company -- Analyst
That's great. And then just wanted a clarification on the royalty agreement. Understanding that will have a positive impact on the gross margin. I believe starting in first quarter of 2020, did it have any impact on the non-GAAP gross margin in the fourth quarter of 2019?
Shabtai Adlersberg -- President and Chief Executive Officer
Yes, yes, definitely, you are so right. Yes. Already in the fourth quarter of 2019 we had a contribution of several hundreds of thousands of dollars in the quarter, but we do expect that in 2020 we will have close to a million contribution on each and every single quarter.
Rich Valera -- Needham and Company -- Analyst
Got it. And then just one more from me if I could. The non-GAAP share count for the quarter, you have a GAAP share count, but I couldn't find the non-GAAP share count for fourth quarter of '19?
Niran Baruch -- Chief Financial Officer
The non-GAAP share count for diluted EPS is 31.4 million shares.
Analyst
31.4 million. Okay, thank you very much.
Niran Baruch -- Chief Financial Officer
You're welcome.
Operator
Thank you. Our next question comes from the line of Mike Latimore with Northland Capital Markets. Please proceed with your question.
Mike Latimore -- Northland Capital Markets -- Analyst
Great. Yeah. Thanks very much. I'm just curious on the cloud, UCaaS, CcaaS, that whole kind of market segments. How much of your revenue comes from kind of the cloud market today?
Shabtai Adlersberg -- President and Chief Executive Officer
So, it's growing. It's not substantial as these days. It's growing. We are deployed with our session border controllers and the management, centralized managed suite and the routing application in both AWS and Azure. We grew, actually in fourth quarter, we grew very nicely with our SBC and Azure and in Teams that is related to the SBC direct route. We are basically putting all efforts toward that. So, it's a process, but it will take time.
Mike Latimore -- Northland Capital Markets -- Analyst
Got it. And then, it sounds like obviously Microsoft's sort of the biggest platform environment [indecipherable] who would be sort of number two and three in the list there after Microsoft?
Shabtai Adlersberg -- President and Chief Executive Officer
We have -- we have number of partners. We have mentioned in the past few names like RingCentral, Amazon, Zoom and a few others. So obviously, we had, in the past also BroadSoft now Cisco, so that's a partner. If I have to call number two in terms of volume of sales, it's Genesys at this stage. All of the others are still not comparable in size to either Microsoft, Genesys and/or BroadSoft Cisco.
Mike Latimore -- Northland Capital Markets -- Analyst
Okay, got it. And then Teams obviously, the Teams subscriber counts grown rapidly. I think it was over 20 million in the September quarter. Do you know like what percent of those Teams users are also using some form of Microsoft voice and where might that go?
Shabtai Adlersberg -- President and Chief Executive Officer
So, you touched on a interesting point. We do see actually, obviously, there's a large installed base Skype for Business users and some of we have seen fourth quarter a number of them starting to move some of their users to Teams. So, I assume that going forward there will be pure new Teams accounts. But at the same time, we will see some of our Skype for Business adding Teams users.
Mike Latimore -- Northland Capital Markets -- Analyst
Got it. And then you talked about a number of large Teams win I believe in the quarter. I assume those deployments will be in a cloud delivery model?
Shabtai Adlersberg -- President and Chief Executive Officer
Yes, yes. When we're talking about Teams, we're talking about cloud deployments. We're talking -- but then, some of the components maybe installed on-prem and session border controllers could be placed either in a cloud and/or on-premise. But all-in-all the majority or the whole implementation is meant to be cloud based. Yes.
Mike Latimore -- Northland Capital Markets -- Analyst
Great. And just last one. How important are acquisitions to your sort of medium-term strategy?
Shabtai Adlersberg -- President and Chief Executive Officer
Good question. Well, we keep growing nicely on the top line, 13.7% this year, on the bottom line more than 30%. It's not crucial. We will -- if there's one area I'd like to look at, it would be more the Voice.ai business where we would like to inject larger, bigger operation into that business unit than we would maybe look more for M&A. So it's not by all means, we have very nice organic growth and we'll keep doing that. It's not crucial. But we will definitely be helpful growing the new business.
Mike Latimore -- Northland Capital Markets -- Analyst
Got it. Great, thanks. Good luck.
Shabtai Adlersberg -- President and Chief Executive Officer
Sure. Thank you.
Operator
Thank you. [Operator Instructions] Our next question comes from the line of Greg Burns with Sidoti & Company. Please proceed with your question.
Greg Burns -- Sidoti & Company -- Analyst
Good morning. You had mentioned the expectation for UC-SIP to continue growing at about 15% to 20%, based on the guidance, I think that's implying like a flattish year for Gateways, but can you just maybe give your outlook for the Gateway business in 2020 based on your revenue guidance? Thanks.
Shabtai Adlersberg -- President and Chief Executive Officer
Yes. UC-SIP will keep growing at the rate we have mentioned. Gateways, we enjoyed a very unique year of up 10%. Obviously, we have done our bottom-up analysis for 2020. It looks like we'll continue to grow on but on a more modest mode. Whether the line will stay flat or grow and/or decline by you know several percent that is still to be seen throughout the year. So, we do bid on our growth on UC-SIP mainly and in on Gateways to hold the line for us, a very profitable business line. But we do not expect growth from that.
Greg Burns -- Sidoti & Company -- Analyst
Okay, thanks. And then in terms of your partnership with Dolby and you're entering the meetings market. What's been the early reception, what are you hearing from customers and maybe what gives you confidence as we go into 2020, and your ability to gain share in that market.
Shabtai Adlersberg -- President and Chief Executive Officer
Okay. So this is a bit premature and we announced the launch in around September, October of last year. We did send the first product, that's a joint product by us and Dolby to several large companies, at this stage some hundreds of units. We know this interest in those units. With the [Technical Issues] think probably expected around February or March this year.
Greg Burns -- Sidoti & Company -- Analyst
Okay thanks. Can you just update us on your tax status in both the US and Israel you know with the tax status [Technical Issues] what do you expect to be full tax payer in Israel, I think you're paying in the US already, but [Technical Issues]
Niran Baruch -- Chief Financial Officer
If you are referring to the expected tax payment in the next one or two years, we do not expect more than $1 million in terms of cash tax payment. We have NOLs and we created the deferred tax asset for that, and that will offset any future tax payment both in Israel and in the US.
Greg Burns -- Sidoti & Company -- Analyst
Okay, great. Thank you.
Operator
