Hi

Is it a normal behavior of Asterisk put a call on hold when receive a Session Progress with media address 0.0.0.0 in SDP? I believe the call on hold should be initiate with a re-invite.

Thanks

  • I think it is normal, the call is placed on hold as soon as the remote media address is null.

    It makes sense because when a 183 is sent, some media is supposed to be sent as with a 200, so placing the call on hold when no media is available sounds logic.

  • The problem the 183 is received with mode sendonly and playbacks an audio, so when the destination playbacks audio, the origin was put on hold.
