Over the last couple of days, I migrated from our outdated asterisk 1.4 PBX to a completely new FreePBX 15.x installation.
Unfortunately, I am still facing one major obstacle, because sometimes it is not possible to connect to (PJ)SIP based extensions, ie call them directly or use them in Ring Groups etc.
When that fails, callers are immediately directed to the extension’s VM application, even though the extension is perfectly available.
Even as I write this, calling my own extension registered on a Grandstream GXP2160 phone works at a 50% chance at best.
I’ve tried debugging the issue by maxing the verbosity and debug level on the server to 9, but as strange as it may seem, if those calls fail, there is nothing in the logs. No hint of a dialplan invoked, no hint of the VM app taking up the call etc, nothing.
If on the other hand the call succeeds, I see the all the expected things in the logs (pjsip debug stuff, dialplan debug stuff and so on).
Before I provide more details on my configuration, I am just wondering if someone has ever been in such a situation as well where the logs would not show anything and maybe has a clue how to at least turn on debugging …
