SIP Forum’s SIPit 33 Slated for December 13–17, 2021 - Advancing STIR/SHAKEN Tops Agenda


The SIP Forum is proud to announce that its next SIP Interoperability Testing Event, SIPit 33, has been scheduled the week of December 13-17, 2021.

Organized by the SIP Forum, the SIPit events are the world’s premier interoperability testing events for SIP, bringing together leading SIP application developers, service providers and IP communications equipment manufacturers to ensure their SIP implementations work seamlessly together in an IP network testing environment.

The purpose of the SIPit event is to test for interoperability of SIP implementations, to determine the source of incompatibilities, inform new standards work, and drive refinement of the specifications. This event is open only to implementers with working SIP implementations, and the results of testing will be completely anonymous – no attribution to companies or individuals, or products or services will be made.

SIPit is organized by the SIP Forum’s Test Event Working Group (TEWG) and serves as a “plugfest” for participating companies to perform SIP interoperability testing with other participants in a live network environment. To date, the SIP Forum has hosted 32 SIPit events around the globe. The previous event, SIPit 32, was hosted by the University of New Hampshire Interoperability Laboratory (UNH-IOL) in Durham, New Hampshire.

Due to the ongoing pandemic, the SIP Forum will be holding SIPit 33 virtually, with remote connectivity to the testing environment, and will once again be hosted by the UNH-IOL. Meetings associated with the event will be held using a variety of video-conferencing services to facilitate discus Advancing STIR/SHAKEN tops agenda sion, brainstorming and debugging amongst the event participants.

The main focus for this upcoming SIPit 33 event will be on Secure Telephone Identity (STI) related technologies.

This includes protocols and industry initiated efforts around STIR/SHAKEN in the U.S. as well as some similar and related efforts happening internationally. The event is designed for implementers that wish to test their devices and cloud and premise-based SIP services that implement the protocols related to STI.
