Android SIP listener onCallEnded delay when call has ended

I am using android built in SIP API. (Example code) I need to do close the session when call has ended (SipAudioCall.endCall() and SipAudioCall.close()).

Problem: when user on the other side hangs up, it takes 0-60 seconds until the listener in

SipAudioCall.Listener.onCallEnded(SipAudioCall call)

is开发者_如何学Python triggered. Also call.isInCall() takes aproximatly the same amount of time to change. I need to close the session/call in order to make another call. At the moment when the user on the other end hangs up first, I have to wait up to 60 sec to make another call.

Why does it take so much time to trigger onCallEnded and is there a way to fix this?

I am using the same code but getting no time delay. I have a audiocall listner on both makecall and take call and when i disconnect a call, i simple call audioCall.endCall() on audioCall object returned by takecall().

If still need some help please comment and i need to ask how are you implementing call reject feature.

Thanks
