Navneet, You need to ignore any Contact header in non target-refresh request/response.
RFC5057 sec5.4 Target refresh requests update the remote target of a dialog when they are successfully processed. The currently defined target refresh requests are INVITE, UPDATE, SUBSCRIBE, NOTIFY, and REFER FYI -Rockson -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Navneet Gupta Sent: Thursday, September 25, 2008 4:38 PM To: [email protected] Subject: [Sip-implementors] Updation of remote information on recipt of ACK Hi I have the following queries regarding remote updation due to ACK request. 1. Scenario is a normal incoming Call. INVITE - 200 OK - ACK. If the contact adress recieved in ACK is different from the one recieved in INVITE, should we update the contact address or the peer? 2. After a successful call is established and the dialog is updated through successful Re-INVITE, should the contact address of the peer be updated with ACK? 3. After a successful call is established, peer sends Re-INVITE which is rejected by us and in the ACK, peer sends new contact address. Should the contact address of the peer be updated with this ACK? what does everyone think?
