asterisk users - Oct 2017 - Asterisk put call on hold when receive 183 Session Progress with media address 0.0.0.0 in SDP

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.

This method is used by telco to playback message to not found user.
