The content on this page is intended to provide information about the SIP Forum's SIPconnect Certification Testing Program associated with SIPconnect v. 1.1.


The University of New Hampshire Interoperability Laboratory (UNH-IOL) and the SIP Forum have collaborated in developing the SIPconnect 1.1 Certification Testing Program. By testing against the requirements of the SIPconnect 1.1 Technical Recommendation, both Enterprise Network equipment vendors and Service Providers can demonstrate compliance and become eligible to display the "SIPconnect Certified" certification mark. For buyers of SIP Trunking services and associated products, the "SIPconnect Certified" mark is a roadmap to interoperability.

Members of this program have placed their support behind the SIPconnect Technical Recommendation 1.1 and agree to offer SIP Trunking services and products in keeping with the guidelines it outlines.

About the Testing

SIPconnect 1.1 Certification testing is conducted by UNH-IOL using scripts developed for the PCSim2 SIP Testing Tool, a testing tool originally developed by CableLabs. For more information about the test tool used for this program, please visit https://www.iol.unh.edu/testing/ip/sip/sipconnect/tool.

The official SIPconnect Certification Testing Program test plan is available HERE.

See below for different options for obtaining certification.

Achieving Certification

The first step for obtaining SIPconnect 1.1 certification is to complete the official SIPconnect Certification Testing Program application form. For a detailed look at the entire process, you may view and/or download a program "Process Overview" diagram.

Once approved by the SIP Forum, the associated SIP Forum SIPconnect Certification Testing Program License Agreement and UNH-IOL SIPconnect Test Service Agreement are competed and submitted, and the testing fee has been paid, testing can be scheduled and pre-testing may commence if desired. After testing has been completed, an official IOL report will be made available and may optionally be submitted to the SIP Forum for certification consideration.

For more detailed information on how to become SIPconnect Certified, please visit the Become SIPconnect Certified webpage.


The UNH-IOL has made an instance of the PCSim2 tool and the SIPconnect 1.1 scripts available for pre-testing. Pre-testing is available for vendors and service providers who have reserved future SIPconnect 1.1 Certification testing with UNH-IOL. The tool may be accessed remotely to test a device located either on site at the IOL, or at the vendor facility.

Remote Testing

A Remote Testing option is available to facilitate testing of devices and services that cannot easily be shipped to the UNH-IOL. For more information about the remote testing option, please visit https://www.iol.unh.edu/testing/ip/sip/sipconnect/remote

For more Information
