Calls transferred or parked dropped after several minutes


#1

We have a user reporting that their calls are disconnected after a few minutes whenever the call is transferred or parked. PJSIP trunk. In the example below, it occurred almost exactly at 5 minutes (talk time after answered from is about 4m 30s).

Noticed hangup code 19 in the logs. Any ideas?

Version: 12.7.6-2002-2.sng7

I don’t know what’s wrong, but it’s very unusual to leave a customer on hold for more than five minutes, listening only to silence. Normally, he would listen to music and/or announcements. Is the silence intentional?

Some years ago, there were bugs, supposedly fixed, associated with the silence generator stopping inappropriately.

At least for a test, set up music on hold and see whether that avoids the drop. If so, and you really want silence, a workaround would be a music class that is silent.
