If UAS can't tell what information it is interested in, then what is the use of INFO method... Also, then how does UAC decide which information to send. regards Himanshoo -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Ranjit Avasarala Sent: Wednesday, September 18, 2002 10:10 AM To: Himanshoo Ks; [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: RE: [Sip] SIP INFO Hi Himanshoo SUBSCRIBE / NOTIFY methods are used to register for specific events like call fowrward, automatic call back , etc. while INFO method is used to convey mid session information.

SIP INFO method is used for sending mid call signaling information. The way information is sent by a UAC to UAS is clear. But I have one basic question: 1. How does the UAC generating this INFO message know that the UAS is ineterested in knowing that event. 2. Also we have SUBSCRIBE/NOTIFY messages in SIP which can be used to subscribe for soem information and then report the same. So in what way is INFO different than these .. Could somebody please answer these questions ? regards Himanshoo _______________________________________________ Sip mailing list https://www1.ietf.org/mailman/listinfo/sip This list is for NEW development of the core SIP Protocol Use [EMAIL PROTECTED] for questions on current sip Use [EMAIL PROTECTED] for new developments on the application of sip _______________________________________________ Sip mailing list https://www1.ietf.org/mailman/listinfo/sip This list is for NEW development of the core SIP Protocol Use [EMAIL PROTECTED] for questions on current sip Use [EMAIL PROTECTED] for new developments on the application of sip _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
