Thank you, Shabtai, and hello, everyone. As usual, we will be referring to both GAAP and non-GAAP numbers on the call. The non-GAAP P&L metrics exclude recurring noncash items. Today's earnings press release contains a reconciliation of supplemental non-GAAP financial information.

Revenues for the fourth quarter were $41.4 million, up 5.6% from the prior quarter and up 9.7% compared to the fourth quarter in 2016. Full year 2017 revenues totaled $156.7 million compared to $145.6 million in 2016. Services revenues for the fourth quarter were $13.4 million, accounting for 32.3% of total revenues. On an annual basis, services revenues increased by 13.8% from the previous year.

Deferred revenues balance as of December 31, 2017, was $39.4 million compared to $31.8 million as of December 31, 2016. Revenues by geographical region for the quarter were split as follows: North America, 39%; Central and Latin America, 7%; EMEA, 41%; and Asia Pacific, 13%. Our top 15 customers in aggregate represented 63% of revenues in the quarter, of which 48% are attributed to our 9 largest distributors.

Gross margin for the quarter was 63.1% compared to 60.9% in Q4 2016. Non-GAAP gross margin for the quarter was 63.6% compared to 61.5% in Q4 2016. Operating income for the quarter was $3.2 million compared to an operating income of $3.6 million in Q4 2016. Full year 2017 operating income was $9.7 million. On a non-GAAP basis, quarterly operating income was $4 million or 9.7% of revenues compared to an operating income of $2.9 million in Q4 2016. Full year 2017 non-GAAP operating income was $12.8 million.

Net income for the quarter was $0.7 million or $0.02 per share. Full year 2017 net income was $4 million or $0.13 per share. On a non-GAAP basis, quarterly net income was $3.8 million or $0.12 per share compared to net income of $2.6 million or $0.08 per share in Q4 2016. Full year 2017 non-GAAP net income was $12.2 million or $0.37 per share compared to $9.4 million or $0.26 per share in 2016.

Our balance sheet remains strong. At the end of December 2017, cash, cash equivalents, bank deposits and marketable securities totaled $58.7 million. Days sales outstanding as of December 31 were 51 days. Operating cash flow generated during the quarter was $8.4 million and $17.8 million for the full year 2017.

During the quarter, we acquired 1.3 million of our ordinary shares for a total consideration of $9 million. As of December 31, 2017, and since we began to repurchase our shares in August 2014, we had acquired an aggregate of 15.8 million shares for an aggregate consideration of approximately $79.7 million.

In November 2017, we received court approval in Israel to purchase up to an aggregate of $20 million of additional ordinary shares pursuant to our share repurchase program. The current court approval for share repurchases will expire on May 27, 2018. We continue to expect top line revenue growth and operating margin expansion in 2018. We expect revenues in the range of $166 million to $172 million, and non-GAAP diluted earnings per share of $0.41 to $0.46.

I will now turn the call back over to Shabtai.

Thank you, Niran. We're very pleased to report strong financial results and continued momentum for the fourth quarter and full year 2017. These financial results attest to a very strong business momentum in the fourth quarter, and in fact, for the second half of 2017. I'm glad to say we see similar such continued trends in January this year.

This is the 10th sequential quarter now that our business momentum picks up fairly steady. All that since the second quarter of 2015 upon the impact of the global oil crisis. UC-SIP, which represents about 45% of revenues, the main business that attracts most of our investments since 2009, continues to grow as planned. And in 2017, we have closed another year of growth that's above 15% annually. Crossing the $65 million of revenues in 2017 and continued growth of 15% annually in 2018 and '19 should bring the UC-SIP business revenue close to $100 million in 2019.

Growth in UC-SIP is driven primarily by our success in the enterprise voice space, where we've gradually become top vendor for delivering voice connectivity and infrastructure for market segments such as the unified communications market and contact center market. Our strategy of close collaboration with market leaders in both segments and strong allies and relationships with large and global system integrators proves to be essential and quite effective in growing our revenues in these market segments.

In parallel, we enjoyed good business momentum in our service provider side of the business, where we see continued annual growth of SIP trunking at a rate that's above 20% across the regions. In addition, we saw continued growth in network transformation project conducted by Tier 1 service providers in several countries, most notably the U.S. and Germany. These are projects intended to help businesses transition from the old world of TDM to an all-IP world.

One important geographical aspect in 2017, we grew significantly in EMEA as compared to other regions. Revenues in EMEA were about 27% of the company overall revenue in the first quarter of 2017 and reached 39% in the fourth quarter of 2017, a jump of over 40% in course of a year.

On the gateway front, which represents also 45% of our business, we enjoyed good business in 2017. Earlier in the year, the plan for gateways called for a decline in revenues of about 5% compared to 2016. I'm glad to say that we actually saw a reverse in the trend and that in fact, revenues grew above 6% compared to previous year. We attribute this mainly to network transformation project in all-IP in North America and West Europe. Understanding that the trend of network transformation is supposed to pick up in coming years, we do not expect any material adverse change in sales of gateways in 2018.

To provide more color as to the relative strengths in the gateway business, I will note the following 2 examples. Second half of the year, we won a large multimillion-dollar RFP for gateways to support the migration to all-IP with one of the world-leading service provider operating in many countries, and we believe that the potential of this win will start to unfold over the next several years.

Also in 2017, in December, we announced that AudioCodes was selected by Thailand True Corporation for IP transformation. True is Thailand's largest broadband internet provider and leading mobile operator with tens of millions of subscribers and the largest fixed-line phone operator in Bangkok area.

Also, according to a latest market report from IHS, we keep gaining market share in the gateway market as we become a consolidator in the space. As indicated previously, we have now become the partner of choice for CPE products in most of the leading all-IP and UC application environments such as Microsoft Skype for Business and BroadSoft. And we are building such position with leading service provider also.

Now to some other business fronts. Let me recap on Microsoft. In 2017, we have seen growth, although slower than in previous years. All in all, we grew in 2017 about 15%, down from about 20% a year ago. We have seen some very substantial increase in sales of products with the new emerging cloud online. Microsoft now places much more focus on Teams, which is a cloud-based collaboration solution that combines chat, presence, voice, file sharing and more.

In fourth quarter 2017, we have not seen yet any impact on revenues. We know that voice will come on, on Teams later in 2018. However, we have strong activity that's planned to support the addition of voice in Teams. Right now, we do support all the different types of work in the markets of environment. We support both on-prem, cloud online and Teams. We've also worked very closely to become an early-stage partner for Teams in connection with Microsoft effort to provide PSTN trunking as the fee-for-service provider services.

In terms of our global activity, in North America, we believe that almost all of the active partners supporting Microsoft Skype for Business and Teams are aligned with AudioCodes. In EMEA, we see growing pipeline of opportunities brought to us by 2 very strong global system integrators. In Asia Pacific, pipeline was growing mainly through Japanese operators. In November, we announced collaboration with SoftBank on Skype for Business. SoftBank, which is a leading Japanese telecom service provider, deploys AudioCodes' product and solution at business customers as part of its Skype for Business Online hosted service.

I'll touch, too, on a large deal we saw on Skype for Business in previous quarter. We have done a very large deal with a large national airline in Latin America. Also, we have won a very big project with an American multinational office supply retail chain, which has over 1,000 stores in North America.

Touching on the front of the SBC, 2017 has been a record year for SBC. All in all, we grew 25% over 2016. The fourth quarter by itself was a record quarter. We grew about 35% over the quarter a year ago and 20% from the previous quarter. So all in all, very strong performance for SBC. I should make note that almost 25% of our SBC solutions sold was implemented in software, so that leads to some improvement on our gross margins.

In terms of the geo-split, North America was the leading regions with about 40%, but then we have lots of activity in West Europe, and we saw activity there, about 30% of revenues. We have got projects on the various fronts. On voice infrastructure modernization of Skype for Business for service providers, managed services for service provider, and then, trunking and access in other area.

Now let me touch on the announcement that we made yesterday. Yesterday we announced a new business unit, Voice.AI. The new unit is intended to leverage on our existing technologies in certain areas, such as speech recognition and call recording, and add to it artificial intelligence and machine learning technologies in order to enhance productivity and to be able to deliver actionable insights from business voice communication.

It is very known that verbal communication remains one of the most effective method for complex and critical business transaction. Yet, most verbal communication is not recorded and is not converted into actionable insight that can help enhance business productivity. If you will compare voice to data, anything that's done with data today in the enterprise, be it e-mails, be it file transfer, be it other forms of data, it is all recorded. It can all be searched. It can all be utilized in order to perform various business processes. Voice is completely abandoned in this regard.

We know that voice is recorded and logged in contact centers for sales calls and sometimes also by companies for service calls, but all in all, we all know that a call on the phone with a business partner, and/or internally, could be a business review which is attended by 10, 15 different people, you have people on the phone. At the end of that meeting, very little of the conversation becomes effective. A few action items are being generated, but really, most of the content, most of the contribution is lost.

So we believe that by utilizing the technology I've mentioned artificial intelligence technologies, on top of our recording and voice recognition technologies can bring a new, very effective solution to that market.

We believe that we're well positioned to help businesses become more productive simply because we can capitalize on a very large global installed base of enterprise partners and customers where we deploy the SBCs and gateways and endpoints, and several of these are located at some very important network junction that are being used to conduct internal and external communication of large companies.

So all in all, we're very, as you can imagine, very enthusiastic about this activity. In fact, if I'll just try to give you a new angle on AudioCodes, you can think now of AudioCodes as really comprising of 2 business units: one which is the traditional, large, which you know its performance for many years, that constitutes, at this stage, above 97%, 98% of the business, is our voice networking unit, and it is about $155 million in revenues. It has global footprint. It has a large installed base of customers and partners. It is growing nicely. It is profitable. And basically, very dominant in growing revenues.

On the other hand, we now have a new business unit that's sort of young, quite advanced in technology, but still very small in revenue. And as you can imagine, we'll have, going forward, we'll have basically developed for ourselves a new growth engine for years to come. If you look on AudioCodes' history, you'll find that in the past 20 years, AudioCodes has always been able to reinvent itself every 6 or 7 years. So we started with technology back in the '90s. We started the gateway line back in 2002 and '03. We started the UC-SIP in 2009. And today, in 2017, we started out the Voice.AI business.

Now coming back to some key points in our financials, Niran has mentioned most of the most important points. I'll just point that last quarter was a very strong one. We grew almost 10% over the quarter a year ago, which tells you a bit about the increasing growth rate for our business.

We have excelled in terms of our operational performance, so operating margin for the first time hit 9.7%. Actually, if you now think about the Voice.AI business basically impact on the main business, you can assume that the main business, the voice networking unit, has performed in terms of operating margin above 10% quite nicely. Cash flow was very strong. This is the third year in a row that we generate above $17 million a year.

The one sore point is the OpEx front. Headcount at the year-end was 698 employees versus 703 by the end of the third quarter. However, we face strong headwinds on the currency front, where the average conversion rate for the U.S. dollar versus the Israeli shekel declined severely. This is the main reason behind the pickup in OpEx for the fourth quarter, which is about $1 million, compared to the previous quarter.

Touching on an annual basis. So in 2017, we grew in revenues 7.7% above 2016 compared to 4.2% regarding growth from '15 to '16. In terms of earning, we basically grew 28.9% in earnings in 2017. And if you compare 2015 to '17, you can see that we have basically doubled earnings in 2 years. Gross margin, a great performance. We hit, for the first time, 62.9% on an annual basis. Cash flow, I've mentioned, very strong. That allows us to be very active on our buyback, and I think you've seen part of the return on investment to investors coming from that process.

All in all, coming now to outlook and guidance, so outlook is very positive on our side. Our main voice connectivity business is well on track, with good position in the market, and we have a new initiative, Voice.AI, which opens for us new horizons and new growth engine.

Reference guidance, as Niran mentioned, regarding revenue, we now guide for a range of $166 million to $172 million. Assuming current business trends continue, we should aspire for 8% to 10% revenue growth over 2017, which will be a pickup from 2017. Regarding earnings, we expect to grow earnings above 20% in 2018, setting for the range of $0.41 to $0.46.

There is much dependence on the new Israeli shekel to U.S. dollar conversion rate. Right now, the rates range about 3.4 to 3.5. It's not favorable, and this is the basis for our guidance. On buyback, as reported, we purchased 1.3 million in fourth quarter '17, and we have a program in place for another 3.5 months, and I assume that we will keep performing on this program.

With that, I've ended my introduction, and I will now turn the call back to the Q&A session. Operator?

(Operator Instructions) Our first question comes from the line of Rich Valera with Needham & Company.

Shabtai, I wanted to ask a question on your new business unit, the Voice.AI unit. Sounds like, doing the math that, that was about $10 million -- would have been about $10 million of revenue last year. Just wondering, what are the products today that comprise that revenue, and how do you think about the growth trajectory of that business and what some of the incremental products are that you might develop that would drive that growth?

Yes, thank you, Rich. Well, in fact, both activities, VocaNOM and SmartTAP, have been much more in a development status in the past few years. So while we have -- and today, we have about 40 people on both activities. Most of it, about 75% to 80%, has been invested in technology development and R&D. We have added activity regarding AI and machine learning and deep, neural networks in 2017.

So we did much less in sales, and right now we are just trying to go upward. In fact, sales have not been higher than, if you will, $2 million or $3 million a year. We do expect though a growth of at least 80% to 100%. In fact, we may incur more growth, but that is just to tell you that where while Voice.AI has been generating less revenues and basically has a negative operating impact, that means that our main business basically has much better operating margin.

Right, got it. And so when you're selling this business, so you're going to sell this as sort of like an overlay, an analytics overlay? I'm just wondering how you're going to market this to your customers.

Okay. Great question. Actually, basically, the basis for the optimism we have is that SmartTAP as a recording solution is being sold for the past 3, 4 years. Now we have tens of customers worldwide using it. We're about to announce our compliance with the new standard that was just made obligatory in 2017. That allows us access to many customers who already implemented SmartTAP as a good infrastructure for recording calls across the organization.

And now think about entering the AI stage. Any company that would use new AI-based technology needs a reference database of calls that were recorded for a long time in order to come up with a new solution. So if you want to process your sales calls, and/or you want to process your service calls, and/or analyze meetings, you need to create a very deep and long database of recorded calls.

And SmartTAP is exactly the solution for that. SmartTAP will allow you to record and make -- record those calls a priori before launching any AI application, just accumulating the calls and creating the large infrastructure that would allow you, when you go to operate these AI technologies, you'll be ready to do so. So we will use SmartTAP; it's a very efficient and install-based solution to upscale our business in Voice.AI.

Got it. That makes a lot of sense. And just wanted to get a little more color on the media gateway market. Sounds like that nicely performed your expectations in '17, and the driver there appears to be significant network transformation projects.

So just wanted to get your thoughts on that business in '18. Sounds like you're expecting a similar trajectory, which would be kind of, I guess, low- to mid-single-digit growth. Is that a fair characterization of your expectations for media gateway?

Yes. Well, the experience we have with the new current environment, which is really driven by those all-IP projects -- indeed, in 2007, when we reversed from a plane of decline to actually finishing upward -- and that is based on activity mainly in North America and mainly in Germany.

As you can -- and we have already seen, in some other countries, some initial steps to move some of the service providers' infrastructure to IP. So we believe this is going to be a stepped, staged process where more countries will enter that.

So understanding that, that needs to be a world trend, but will take place in steps in many countries over the years. We have no reason to believe that we will see much change, but we will have to go through 2018 to indeed assess whether that assessment or that assumption is true or not.

Got it. And just one more from me on the stock buyback, you've been pretty consistent with buying back stock now for a while. Is there any reason to think that would change in 2018?

We always thought when we did it that, that would be one of the best investment we could make for us with cash flow that we generated. In 2019, I think we will look into that as well. That would be a continued theme in our mind.

But at the same time, maybe with the new Voice.AI, we will be looking around for more technology and more activities that can augment and further jump the operation. So yes, it's always an assessment of the share price, the proceeds, the funds we have and what's lying ahead and what makes sense more to do, but yes, we will be active.

Our next question comes from the line of Dmitry Netis with William Blair.

Nice ending to the year, guys. Well done. A couple of questions for me. Just on this annual guidance, kind of following up on Rich's question, I think if I hear you, you [blessed] the low- to mid-single-digit growth on the media gateway front, implied in that guidance would be over 20% growth in UC-SIP. So I'm just trying to get a better perspective. Is that the expectation, that the UC-SIP business will grow 20% in 2018?

We have not specified 20% as the growth factor. We will definitely -- we believe we should grow at least 15%. In the past, we quoted more 15% to 20%. It remains to be seen.

We see -- well, the main business line in that category, the SCB, grew above 20%. We have few more lines there, including our business routers, the Microsoft cloud appliances, the phones, IP phones and the management software. So all in all, I will not change guidance as to above 20%. I think we will be above 15%.

Okay, about 15%. So then, what -- where -- so maybe we could ask the question differently, then. Service revenue growth versus product growth, how are you thinking about that? What is the service revenue growth expectation for 2018?

So service will keep growing. In the past 2 years, I don't have the data in front of me, but I think we grew definitely above 10%. I think we grew somewhere, 10% to 15%. We see no reason for the trends on the service side to change, but services are growing faster than products.

That may change when we start to grow more Voice.AI where products are relatively young and the majority in revenues will be from product versus services. But all in all, for the networking unit, services grow faster than products. On the Voice.AI, we'll see products growing faster.

Got it, okay. And then just kind of looking at the -- on the Q1 side, I'm actually modeling it down just purely given the seasonality factor in the March quarter. What -- you're coming off of a very strong December. Was there some pull-in business? Was this natural demand? How are you feeling starting the year?

It sounds like you're upbeat given the guidance, so what should the model for Q1 look like? Are we looking more of a flat quarter in March, down quarter in March? Give us a sense of how we should be modeling it.

Right. So traditionally, we have usually factored in a lower first quarter versus the fourth quarter. So in our budget and plans, I think we factored in about 2% or maybe 3% decline.

The trends in January point to a better quarter. So right now we're still in the first week of January, or second week. We're not that active, so it's still early to call on the quarter, but all in all, we definitely have a good start, better than anticipated, for the first quarter of 2018.

All right, that's helpful. And then a couple questions on the product side. So I look at the SBC. You had the record year and quarter, very strong, obviously. What do you attribute this to? Was this more of a competitive environment changing vis-a-vis the Sonus/Genband, or maybe Acme Packet? Anything you can tell us, a, what drove the business strength; and b, what the competitive environment looks like, would be good.

Okay. So to give you a better sense, first, we operate in 2 different market segments, the enterprise and service providers. In the enterprise, we're sitting very well. The fact that we are dominant and leading on the Skype for Business front and Teams, and also on the contact center, which I haven't mentioned so far, but the contact center has been very good for us. And SBC is a [fully] and important product in that area.

So all in all, in the enterprise space, we feel there's less competition at this stage because of 2 key factors. One, one of our key competitors, Ribbon Communications, is focusing substantially more on service providers. Second is that to sell session border controllers in the enterprise market, you need to partner with the application vendors. And there's another player there, Oracle. We've not seen that Oracle is playing a partnership game with our allies. So all in all, the environment in the enterprise space is fairly good, good for us. We don't see much competitive pressure there.

On the service provider, which is, on a company, by the way, on a company scale, service provider is about 20% of our revenues. We have no play at all in the core SBC market, which is -- usually competition there is between Huawei, Ericsson and Nokia. On the access part of the network, we do have, definitely, we do have a play, and we feel that we are fully competitive there. So we're putting a lot of emphasis on the access and cloud SBC. So that gives you a picture on this.

And then, back to the enterprise side. Is there any change from Cisco/BroadSoft combo? I mean, are there more aggressive, less aggressive? What are you seeing out of that combo?

It's too early to make a call, I think. The transaction has not closed yet. From some discussion we had, we have no sign that things are going to change dramatically, but again, we will have to live through that experience. So all in all, we don't see much change on that front.

All right, good. And then last question on the network transformation, almost a bit of a follow-up to Rich's question, and the way I want to frame it is this way, how many network transformation projects, so maybe RFBs, are out there? Is there a number, or do you see that pace of these projects accelerating at this point in time?

And what are you exposed more toward, either the Nortel DMX replacement or the Alcatel-Lucent's 5ESSes? Where do you see you can have the best bang for your buck given the product you have, in (inaudible)?

So -- yes, okay. So let me go one by one. North America is the most active in this network transformation process, and that process is going on for quite a few years. We are working with several such companies, and we don't see, at this stage, I think, the process in North America has not crossed yet. I would say even the -- in my mind, even 30% or 40%, in terms of the overall potential. We -- so we're definitely working with some [no names], as have been mentioned in the past, like Verizon and a few more operators.

In Germany, Germany is the second country, with much activity working with Deutsche Telekom. We're working with -- in 2017, by the way, we enjoyed much success. I think we can count between 6 and 8 different new service providers in Germany which are starting to work with us on that. We know there's activity in France, in the U.K. We've seen some in Switzerland.

I've mentioned True from Thailand is a representative of the large, very large, tens of millions of subscribers from Asia Pacific. But we know for a fact that in Asia Pacific, that whole process is really being pushed more into the 2020, 2025 year.

I just mentioned another one, huge service provider, that is operating in EMEA and other region, and what we want, and our [fees adjust] was decided, second half of 2017, which means we can expect another 5, 7 years of deployment of that product. So all in all, I would say again that the whole process is really in its infancy, and we expect some very meaningful years ahead of us.

All right, that's very helpful. And just to clarify, you said that the penetration rate in that network transformation initiative hasn't quite crossed the 30% yet. Is that fair?

That's my -- I said 30 to 40, but that's my personal assumption, yes.

There are no further questions at this time. Mr. Adlersberg, I'll turn the floor back to you for any final comments.

Okay, thank you, operator. I would like to thank everyone who attended our conference call today. With good business momentum and execution on our plans in the fourth quarter and the full year of 2017, we believe we are on track to achieve, in 2018, another year of growth. We look forward to (inaudible) you and to see you participate in our next quarterly conference call. Thank you very much. Have a nice day.

Thank you. This concludes today's teleconference. You may disconnect your lines at this time. Thank you for your participation.
