SIP Parity Activity Group

The IMTC SIP Parity Activity Group provides a forum for IMTC member companies to cooperate and pool resources on SIP Parity issues of common interest. The SIP Parity Activity Group focuses on multimedia telecommunications applications including providing a video profile for SIP that matches all the capabilities of H.323.conferencing.


What We Do

The main activities of the group are to:

  1. Organize interoperability SIP Parity test efforts (both virtual and face-to-face). This would be done in cooperation & coordination with both the Conferencing Interoperability Activity Group and with SIPit (where practical).
  2. Provide a forum for members to agree on an overall SIP profile for video. The objective is to bring it to full feature parity with H.323 video communications.
  3. Educate members on most recent developments in SIP standards and market evolution



Liaisons

The IMTC collaborates and has liaison relationships with several standards development organizations – ECMA, IETF (RAI area and SIPCORE working group), ITU (SG 16), SIP Forum, and UCIF. Learn about the liaison activities this group is maintaining with external organizations.
