Hi Have a VoIP service connected, and **Registered with VOIP Host** is showing on the settings page. When I trigger an alarm and the notifiaction pipeline calls me up I get no sound when I pick up. I tried to monitor the data in wireshark, and when going to the Telephony/RTP/RTP Streams, I find the sound of the call, and I can play the call. The call sounds exactly like it should. What could cause that stream not to go all the way to me? Wrong RTP port? ---

Firewall or NAT somewhere along the way. Possibly also a codec not supported by your VOIP provider. ---

Solution were setting the Public and Local Bind Address fields to be blank.
