Hello Haven't been able to find a reference to this scenario.
(convert to Courier or "fixed width font" to see properly) UEA UEB | -------------> | | INV SDP offer | | version 1 | | | | <------------- | | 200 OK SDP answer | | | | | | -------------> | | INV new SDP offer | | version 2 | | | | <------------- | | 606 Not Acceptable | | | | | | -------------> | | INV new SDP offer | | version no? | | | | | What should be the version of the new offer? My impression is 3 (version should always increase) but in a related call flow I have received an answer that says "fallback to previous state also means previous version number so in new offer previous version is increased by 1 so new version should also be 2 .... Anybody has any rfc references at hand?
