Hi I have following scenario - 1. UA1 sends INVITE to UA2 with Supported: 100rel header 2. Call is established (180, 200, ACK exchanged) 3. UA2 wants to put the call on hold and sends re-INVITE to UA1. This message contains Require: 100rel header. 4. UA1 rejects this request with 420 Bad Extension.
Is it OK to include Require header with 100rel in the re-INVITE, UA1 has already showed that it supports this extension. Why should UA1 reject this message with 420 response. Thanks Kchitiz _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
