Hi. I think this is maybe supposed to happen if the remote end sends a reinvite to put the call on hold, instead of simply sending music-hold audio down the line?
It seems a bit weird though.
I’m in the UK, using Gamma as a SIP trunk. If I call my EE mobile phone from the Asterisk system, and put the call on hold from my mobile/cell phone, I hear our local music on hold. I would normally expect to hear either silence or an occasional beep.
Reading back over some old discussions that I don’t really understand, it seems that this is (was?) designed behavior for Asterisk if there is no audio to play, but I wonder if there’s any way to alter it? We are using an older build of Asterisk if that makes a difference - 13.15.0
