This is a collision case of a provisional reliable 180 response and a BYE Request. The application on the callee side has sent a 200 OK response, and the response is left pending in the SIP stack. Then the collision occurs and the BYE is indicated to the application. [ABN] Callee should have stopped sending 180 after 487 sent for INVITE. the correct scenario should have been UAC UAS | INVITE | |----------------------->| | 100 TRYING | |<-----------------------| | 180 RINGING | |<-----------------------| | 180 RINGING | |<-----------------------| <------- 200 OK INVITE is buffered (not sent out from stack) | BYE | |----------------------->| | 200 OK BYE | |<-----------------------| | 487 | |<-----------------------| | ACK | |----------------------->| ---NO call established--- Regards, Madhuri _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors The information contained in this message may be confidential to Kodiak Networks, Inc. and its subsidiaries and protected from disclosure.
