It should be done at the Transaction Layer. One should not be sending such an invalid re-INVITE to the application, increasing the overhead on the application.
Thanks, Bharat -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Tuesday, July 08, 2008 1:16 PM To: [email protected] Subject: [Sip-implementors] Re-invite without To Tag Hi All, The re-invite should be processed, by UAS, as the request within the dialog. In this point, the re-invite without the To tag should be discarded, right? While, here is a problem, should it done by the Transaction layer which is responsible for the dialog state to detect such a invlid re-invite, or by the transaction user, i.e, the application user of the SIP stack? In other word, should a re-usable SIP Stack software be capabable of detecting a re-invite without To-tag?
