SIP Forum Begins Work on SIPconnect v.1.1
The SIP Forum reached an important milestone when it formally adopted version 1.0 of the SIPconnect Technical Recommendation this past January, 2008 with the unanimous approval of the SIP Forum Board of Directors. At the same time, the Board announced the formation of the SIPconnect v.1.1 Task Group.
The formal adoption by the SIP Forum Board of the SIPconnect 1.0 Technical Recommendation is based on recognition that the recommendation has been through credible peer review, including broad membership and significant community review, that it is stable and is well-understood, and that it is believed to have resolved known design choices.
