If your stacking is listening on some port that you specified in your Contact. Then you are expecting response/request on that particular port. Your stack probably will not listen on any other port. So, the request or response coming to other port will get drop. It's not practical to listen your stack on several ports to receive SIP request/response message.

Rangnathan Sent: Sunday, June 04, 2006 12:15 AM To: Sip-Implementors Subject: [Sip-implementors] In-dialog Requests and Dialog Contact Address Hello! I still have a doubt about in-dialog requests. The scenario is as follows: 1. A UAC creates a dialog and specifies a contact address to which subsequent In-Dialog requests should be directed. 2. After the Dialog is established, a request arrives at the stack through a port that is NOT the same as the port specified in contact address specified but with the SAME From and To tags of the Dialog. The CSeq number is also OK. Should the stack consider this request as a valid in-dialog request or consider the request to be out of dialog ? Thanks in advance for responding to this question.
