Hi All,

I have a basic query regarding offer-answer model.
Why can't/don't UAC & UAS use the same session-id in "o=" line of the SDP? I agree that RFC 4566 define session-id as <sess-id> is a numeric string such that the tuple of <username>, <sess-id>, <nettype>, <addrtype>, and <unicast-address> forms a globally unique identifier for the session, which makes it different for UAC & UAS but i want to know what advantage does give it over same session-id as we have same call-id.
