Hi Kaushik,

If I understand the problem you have correctly, (please next time post logs/console ouputs leading to your diagnosis of the problem, they can be useful even if you’re 100% sure about the nature of the problem) you should be able to follow the instructions from step 3 in this link to solve your problem.

Hope this is useful,
Gianni

Hey,
I just figured out the problem is because of ALSA ( I am using Ubuntu 14.04 ). It is because of ALSA that I am not able to get the audio. Can someone help me how to go about the whole ALSA thing to get the audio
Thanks,
Kaushik

You might need to put the conf_connect calls in the onMediaState() callback. See if that works.

      This is the logic of the goal I am trying to achieve. It should call, when confirmed, should play an audio wav file and hangup after that
      I am able to call, but when the call is lift, I cannot hear the audio. 
        if self.call.info().state == pjsua.CallState.DISCONNECTED:
            current_call = None
            print 'Current call is', current_call
            in_call = False
        elif self.call.info().state == pjsua.CallState.CONFIRMED:
            #Call is Answred
            print "Call Answred"
            wfile = wave.open("message.wav")
            time = (1.0 * wfile.getnframes ()) / wfile.getframerate ()
            print str(time) + "ms"
            wfile.close()
            call_slot = self.call.info().conf_slot
            self.wav_player_id=pjsua.Lib.instance().create_player('message.wav',loop=False)
            self.wav_slot=pjsua.Lib.instance().player_get_slot(self.wav_player_id)
            pjsua.Lib.instance().conf_connect(self.wav_slot, call_slot)
            sleep(time)
            pjsua.Lib.instance().player_destroy(self.wav_player_id)
            self.call.hangup()
            in_call = False
This is some part of the log when I run the program

17:03:26.375    pjsua_aud.c  .....Creating file player: test.wav..
17:03:26.375   wav_player.c  ......File player 'test.wav' created: samp.rate=16000, ch=1, bufsize=4KB, filesize=166KB
17:03:26.375    pjsua_aud.c  ......Player created, id=0, slot=2

17:03:28.141    pjsua_aud.c  .....Destroying player 0..
