Dear All,
I have query regarding the Session version in SDP. I know if we are making
any changes in SDP then from 183 to 200OK with SDP then there will be
increment in session version from 183 <session version = 1> to 200 OK
<session-version=2>. However i have 2 doubt as below. Can you please help
me on this.
1) Is that Value should be increment by 1 only? I mean suppose in 183
w/SDP we have Session Version =1 , then is that mandatory that we should
have "session-version=2" or it can be 3 directly. OR
2) if in 183 w/SDP and 200 Ok we had the same value but when "re-invite
happened then SDP was same but "session-version" value incremented from 1
==>3 directly. I feel it should be 2 (i mean increment by 1 only). Please
advise if my understanding is correct.
RFC 3264 requires that it be incremented by 1. But if you are on the
receiving side I suggest you be lenient about this.
Thanks,
Paul
