SIP Trunking – Your First Step to a Future-Proof Communications Network

Beginning the Journey to Enterprise Voice Network Modernization


There’s no doubt about it: a huge shift in voice communication networks is well underway, as enterprises move away from PSTN towards IP.

One of the core reasons for this change is that telecom carriers themselves are transitioning from TDM to SIP, in an effort to reduce their equipment’s operating costs, power consumption and footprint, while taking advantage of advances in voice technology. As a result, within a few years, major carriers will simply declare end-of-service on their TDM and ISDN switches.

On the customer side of the equation, market data shows huge numbers of enterprises leaving behind traditional PSTN voice services as they align themselves with the changes occurring in service provider networks. According to a recent report by IHS, 71% of organizations are making the switch to either a centralized or hybrid SIP trunk. In fact, they predict that between 2015 and 2020, the number of SIP trunk connections will have more than doubled, from 20 million to over 45 million.


A Meaningful Impact

As a large, distributed enterprise, moving your voice communications to all-IP infrastructure opens up a whole host of significant benefits. Besides the immediate financial benefits, the transition to SIP trunks allows organizations to centralize and consolidate trunks, for optimal utilization and the ability to leverage economies of scale.

While making the move to SIP trunks, you can take the opportunity to modernize and centralize the management and control of your network as a whole, to assure service quality, remove blind spots across the network and improve security. More efficient management will contribute to the reduction of your IT staff’s day-to-day workload, so they can allocate more time towards finding innovative ways of driving further efficiencies throughout the organization.

Now that you are using your existing data network (WAN) for voice communications, and having implemented more efficient call routing, monitoring and dial-plan configuration, your internal and long distance calls can be routed through your IP network to achieve substantial savings. As you minimalize the costs of internal communications across your enterprise and reap the benefits of least-cost routing (LCR), you can expect to reduce your total communications expenses by up to 38% (based on information gathered from AudioCodes’ customer base).


The Way Forward

A solution such as AudioCodes’ Universal Communications Architecture (UCA) will allow you to achieve all this, and more. UCA enables large enterprises with multi-vendor communications systems to modernize their voice networks efficiently and cost-effectively. It achieves this by integrating communications silos, connecting with SIP trunk services and utilizing the corporate IP network to optimize call routing.

UCA features AudioCodes’ session border controllers (SBCs), global end-to-end call routing and policy management, and advanced VoIPerfectTM voice optimization technology, enabling the creation of a universal network that offers high voice quality, without having to replace existing communications platforms.

As we have seen, there is much more to all-IP voice communications than just SIP trunks. AudioCodes’ UCA solution enables you begin to derive maximum benefit from the all-IP world today, by delivering a future-proof voice infrastructure that is easy to manage, maintains corporate security and delivers significant capital and operational cost savings.

Defining the Future at BroadSoft Connections 2015


AudioCodes All-IP TransformationBroadSoft Connections is one of the highlights of the telecom industry year, bringing together service providers from all over the world to learn about new developments and technologies at one of the busiest events for this community. The day before it opened, I had the chance to chat briefly with Michael Tessler, CEO and President of BroadSoft, while he was on his way to the Ballroom. Michael expressed his excitement about the great turnout and scale of BroadSoft Connections this year. As Michael mentioned in his opening session, BroadSoft powers 41% of UCaaS seats globally, so the popularity of the event is no surprise to us. AudioCodes was honored to be a Platinum Plus sponsor this year, allowing us to have a larger presence and to showcase our hot topic of “All-IP Transformation” with perfect timing.

The process of transforming to an all-IP network is at a pivotal stage and was a key discussion point during our meetings with service providers. Service providers are looking for ways to migrate their ISDN infrastructure to pure IP in a simple but reliable way without hefty spending. This was also the main topic of conversation at the Network Transformation breakout session, where together with BroadSoft and Cavell, I had the opportunity to discuss the main message that “there is more to IP Transformation than just SIP Trunking”. In other words, service providers can leverage the process of migrating their existing ISDN network to build the necessary infrastructure and develop plans for expanding their service offering and increasing ARPU.



Some other highlights of the event included:

  • BroadSoft’s announcement that it has selected AudioCodes’ SBCs for the BroadCloud SIP Trunking service. SBCs are considered an essential element of SIP trunking services – offering interoperability, security and high quality of service as well as enabling the delivery of new, additional services in the future.
  • Our NFV demonstration at the booth was a big hit. By using NFV tools we can deploy a Virtual CPE where local functions such as router, firewall and SBC are instantiated from the cloud, up to the point where on-premises devices will auto-configure themselves with the BroadWorks platform.
  • The debut of AudioCodes’ new, high-scale analog gateway – the MP-1288. The event was the first time our customers could see this new device that addresses mid-market enterprises and verticals such as hospitality, healthcare and education. The MP-1288 enables enterprises to continue using their existing cabling and analog phones when migrating to hosted PBX solutions thus avoiding the costs of a rip-and-replace upgrade.


After countless discussions and meetings, we left the event truly inspired by how the BroadSoft community is defining the future of the service provider industry.


See you next year!
