Hi,
RFC 2327 specifies the origin field as :
origin-field = "o=" username space
sess-id space sess-version space
nettype space addrtype space
addr CRLF
Isnt it must to have "sess-version" value in the SDP of re-invite to be
different than the value in original invite, given the reinvite does change
the session parameters ( for ex : put a call on hold etc ). ?
I am seeing a vendor implementation where ( in o= field ) sess-id and
sess-version remain same but "addr" changes. Should this sdp offer be treated
different than the first one ? Shouldnt combination of "sess-id" and
"sess-version" uniquely identify a session ?
TIA.
Manish
