Interoperability is key to a smooth SIP trunking deployment

The SIP Forum has launched a new SIP trunking interoperability testing initiative intended to spur adoption of the SIPconnect 1.1 technical specification, which is a standards-based approach for SIP trunking between IP-PBXs and VoIP service provider networks.

Interoperability is a key issue for SIP trunking deployment. The enterprise's IP-PBX, service provider and edge devices need to work together for a successful SIP trunk deployment.

The SIP Forum was formed by IP communications companies to advance the adoption and interoperability of IP communications products and services based on SIP. It recently established the SIPconnect-Interoperability Certification Task Group to develop appropriate test plans and conformance tools for SIPconnect 1.1, to identify interoperability challenges and to develop a process for resolving industry disputes.

The ultimate goal of the task force, which is chaired by Alan Johnston of Avaya and Robert Kinder of Cox Communications, is to speed adoption of the SIPconnect 1.1 technical specification and create a formal testing certification program for compliance.

The task group has set up the SIPconnect-IT 2012 conference, which will bring together application developers, equipment vendors and service providers to test the SIPconnect 1.1 specification in a live network environment. The event will be held Dec. 3 through Dec. 7 at the University of New Hampshire Interoperability Laboratory.

According to the SIP forum, there are a number of benefits to adoption of the SIPconnect 1.1 specification. For enterprises, SIPconnect reduces the need for a gateway at the end user's site and speeds the delivery of new features from the service provider or the IP-PBX vendor.

For value-added resellers, the SIPconnect reduces the complexity associated with connecting the SIP trunk to the legacy TDM network.

For equipment and software vendors, SIPconnect reduces the time and resources required to verify interoperability in the network.

For SIP trunking service providers, SIPconnect enables network services to be rolled out more rapidly, reducing the time to revenue for new services and features.

In order to ensure smooth SIP trunking migration, enterprises should ensure that the service providers, PBX vendors and edge device manufacturers they select use the SIPconnect standard.
