hi, 1: It depends on your application logic, reject the call is one possible action.
2:the format of SDP in PRACK to reject the Offer should follow the rule mentioned in RFC3264. regards Peili Xu -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Hema Ramamoorthy Sent: Wednesday, September 14, 2005 8:02 PM To: [email protected] Subject: [Sip-implementors] PRACK rejecting Offer SDP in 183 Hi, I need help on the following issue. My call flow goes on like this. INVITE (No SDP) -----------------------> 100 TRYING <----------------------- 183 Session Progress (Offer SDP) <----------------------- PRACK ------------------------> This PRACK message rejected the Offer SDP by sending an Answer SDP with Port value as 0. My queries are: 1. What should be done next by the UAC? Should it send a 4xx response? 2. What will be the format of the SDP received in the PRACK? Will it list out any of the codec capabilities? Please provide me some RFC which can give information on this. Thanks & Regards, Hema Ramamoorthy. _______________________________________________ Sip-implementors mailing list [email protected] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors _______________________________________________ Sip-implementors mailing list [email protected] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
