Dear All,

I have one call scenario where my termination is sending the SDP in 183 as
well as in 200 OK also. As far as i know if we are getting SDP in 183
session progress then my UAC can ignore the SDP in 200 OK. Also most of the
time SDP is same.

But here i noticed the slight difference of "Session Version". Here when my
termination is sending 188 Session Progress with SDP is sending the SDP as
below.

I can see that  my Termination is incrementing  "*Session Version*" for SDP
in 183 & 200 OK in same dialog..

*183 with SDP*

S_OWNER : o=TLPMSXP2 22660 *22660* IN IP4 69.90.230.210
S_NAME : s=sip call
S_CONNECT : c=IN IP4 69.90.230.217
TIME : t=0 0
M_NAME : m=audio 59072 RTP/AVP 18 4 8 98

200 OK with SDP:

S_OWNER : o=TLPMSXP2 22660 *22661* IN IP4 69.90.230.210
S_NAME : s=sip call
S_CONNECT : c=IN IP4 69.90.230.217
TIME : t=0 0

Could anyone please let me know if that is okay to increment the session
version and if any supported document is there?

Thanks,
Nitin
