Bharat, You are mostly correct. One point I want to add is you might get SDP answer in reliable response instead of 200, though this is seldom used in real world, but It's totally correct as per spec.
You can also check out RFC3264 sec 8.3.1 Modifying Address, Port or Transport FYI -Rockson -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Wednesday, August 06, 2008 1:42 PM To: [email protected] Subject: [Sip-implementors] SDP Query - reINVITE with IP Address inconnection info field updated. Hi all, Say we have call between Party A and Party B. When both parties are in call, Party A sends out a re-INVITE to Party B updating the IP Address in the connection information field in SDP. In the Initial SDP exchanged c: IN IP4 1.2.3.4 In the re-INVITE sent c: IN IP4 5.6.7.8 As far as I understand, once Party A receives a 200 OK from the Party B for the re-INVITE sent; there won't be any media arriving on the IP address 1.2.3.4. Further exchange of real time data will take place at IP address 5.6.7.8. Am I right? Is there any RFC/Draft that explains handling of this behavior?
