HI Kishoresowdi,
The request sip message should also contain the
contact header field as follows
SipUserAgent::sendTcp TCP SIP User Agent sent message:
----Remote Host:192.168.1.123---- Port: 5060----
REGISTER sip:bob.com SIP/2.0

Via: SIP/2.0/TCP 176.25.1.211;branch= The branch id

And then The Invite field should also contain the
contact field but it should contain the SDP part of
the message also. And about the second part you have
asked can you be little more clear on that. So that
i can try and help u out.

Hi there ,
RFC 3261 says concact header field is added by
UAS while
responding the request .The contact header feild
contains an address where UAS
would like to be contacted for subsequent requests in
the dialog . How
about contact header feild in requests ? . Does INVITE
request only do
contain contact header feild or other requests may
contain ? .
