AudioCodes' Webinar Explores Power of SIP Trunking Interoperability

By Susan J. Campbell, TMCnet Contributing Editor


The drive toward Unified Communications (News - Alert) doesn’t appear to be wavering as companies throughout the global marketplace want to streamline costs and enhance capabilities. As a result, there is an increase focus placed on SIP trunking and what it can do to protect the convergence of voice and data onto one network. 



In a recent webinar, AudioCodes explored the potential in SIP Trunking with Microsoft (News - Alert) Lync, highlighting how the company is solving the interoperability challenge as UC and Microsoft Lync continue to sweep the business world.

Companies are leveraging the new and powerful communications capabilities in the these solutions, and are looking for ways to integrate SIP trunking to lower local and long distance toll charges. There can be, however, substantial interoperability and security challenges in integrating SIP-based Lync with SIP trunking that are difficult to overcome. 

By accessing this archived webinar, you will be able to explore the underlying interoperability and security challenges that exist today, as well as learn about integration techniques that allow businesses to use both Microsoft Lync and SIP trunking to reduce operating expenses and improve efficiency. 

As demonstrated in this archived webinar, SIP is a very good protocol and conforms to the current stands, and there are a number of vendors out there supporting SIP. It can ensure least cost routing, companies can leverage ISP connections and it is very good for carrier peering. There are specific topics to consider when thinking about SIP trunking, specifically availability, uninterrupted failover, call quality, redundancy, the demarcation point between the service provider and the customer, and more. 

In terms of security, companies have to evaluate a number of different things, including physically secure sites, secure signaling, secure media, and their firewall configuration. Most importantly, they have to implement Enterprise Session Border Controllers to protect the network edge. 

There are interoperability challenges that exist, including common activation issues that can occur include private/public IP setting, use of the G.711 codec, the need to add a single trunk first and then add redundancy, the demand to begin with a central site before extending to branch sites, and the call to add security after initial call success. 

Firewall challenges also exist, including the need to validate that network address translation will support SIP and that it is SIP aware, as well as verifying that ALG devices are configured correctly. If this configuration is lacking, symptoms include 1-way audio, clipping, signaling timeouts that lead to a fast busy. 

In all, there are six keys to evaluating vendors: geographic coverage; pricing models; moving numbers to new providers, E911 support; caller ID support; and SLAs and turnaround times.
