[SIPForum-techwg] Focus on simple PSTN?

[Russell Bennett]

John,

Our proposal document was not an increment to SC1.0 for sure.  We had a big internal debate about whether we should build on SC1.0 or submit the spec that we had already.  In the end, Rich Shockey resolved that one for us and asked for the spec that we were using internally.

The proposal can be viewed as attempting to achieve the same goals as SC1.0 - i.e. define the mechanism for SIP/RTP voice connectivity between an enterprise and a service provider - aka "SIP Trunking".  It is more prescriptive and attempts to be a stand-alone spec - which is a different approach to 1.0, however, the net result is the same.

[JRE] But is the Microsoft really an incremental approach? Backwards
compatibility with 1.0 seems to be lacking somewhat. At first read it
looks more like a big bang replacement?
