Hi In pjsua, if there is an incoming call and user hangs up the call ( it sends '603 decline' code in reply of INVITE ), disconnect event (on_call_state callback) comes immediately after sending 603. But if there is an outgoing call and user hangup the call ( it sends CANCEL message in reply), disconnect event comes after getting reply of CANCEL message. It will wait for reply of CANCEL message. If there is a delay in network, user is not able to disconnect the call until get reply from other end. What I want is , if hangup is called, it will immediately disconnect the call without waiting for reply from other end. How can I make PJSUA to do that? please help Regards Rohit yadav -------------- next part -------------- An HTML attachment was scrubbed...
