I’m using Asterisk 16.16.1 with PJSIP.
Problem is that after one or two days, the PJSIP endpoint to the ISP stays/hangs “in use”. This endpoint is monitored on BLF, so it seems that the line to the ISP is always busy.
But there are no active channels, nor any other active endpoints.
New incoming or outgoing calls work fine, but don’t clear “in use”.
Just reloading PJSIP, (sometimes restart asterisk) clears the state to “idle”.
I observe this behavior since two years now, it started in Asterisk 13.
Unfortunately I have no idea how to debug this or what might be the cause.
In the dialplan every extension is ending in Hangup(); Return() to terminate the channels correctly.
Any help or hints are really appreciated.
