Hi Adrian,

I was tried so many code to check and no-luck, seem i am get stuff on that and could not get any result with playing audio and more further action.

I hope you can give me some more document, or idea to check more.

I custom sip-session script to pickup the call. Add some code in _NH_SIPSessionDidStart

in IncomingCallInitializer(object):

Just to play audio on that session. code somethinglike

def _NH_SIPSessionDidStart(self, notification):

        notification_center = NotificationCenter()
        session = notification.sender
        audio_stream = notification.data.streams[0]
        notification_center.remove_observer(self, sender=session)
        IncomingCallInitializer.sessions -= 1

        ui = UI()
        ui.status = 'Connected'
        reactor.callLater(2, setattr, ui, 'status', None)

        identity = str(session.remote_identity.uri)
        if session.remote_identity.display_name:
            identity = '"%s" <%s>' % (session.remote_identity.display_name, identity)
        send_notice("SIP session with '%s' established" % identity)
        for stream in notification.data.streams:
            if stream.type == 'audio':
                send_notice('Audio stream using "%s" codec at %sHz' % (stream.codec, stream.sample_rate))
                if stream.ice_active:
                    send_notice('Audio RTP endpoints %s:%d (ICE type %s) <-> %s:%d (ICE type %s)' % (stream.local_rtp_address, stream.local_rtp_port, stream.local_rtp_candidate_type, stream.remote_rtp_address, stream.remote_rtp_port, stream.remote_rtp_candidate_type))
                else:
                    send_notice('Audio RTP endpoints %s:%d <-> %s:%d' % (stream.local_rtp_address, stream.local_rtp_port, stream.remote_rtp_address, stream.remote_rtp_port))
                if stream.encryption.active:

                    send_notice('RTP audio stream is encrypted using %s (%s)\n' % (stream.encryption.type, stream.encryption.cipher))
        if session.remote_user_agent is not None:
            send_notice('Remote SIP User Agent is "%s"' % session.remote_user_agent)

        send_notice('start to play audio to cehck %s' % dir(session))
        filename = '/usr/share/sipsimple/resources/sounds/pet0.wav'
        player = WavePlayer(audio_stream.mixer, ResourcePath(filename).normalized)
        notification_center.add_observer(self, sender=player)
        audio_stream.bridge.add(player)
        player.play().wait()
        player.stop()
        audio_stream.bridge.remove(player)
        notification_center.remove_observer(self, sender=player)
        session.end()
        session = None
        send_notice('start to play audio to cehck done')

The call is answered and nothing to play, no log to show error and i see that something death on that call, i could not exit the call as well.

Can you help me please.
