Non-TLS extensions fail until server reboot

FreePBX 14.0.13.24
Asterisk 13.29.2

Our Asterisk server is regularly failing in a big way. UDP users can connect to the server, but calls to other extensions ALWAYS go to voicemail. Additionally, they can’t see anyone else who is online.

TLS users do NOT experience this issue.

Rebooting the server solves this issue for a few days.

We see this line a lot:
[2020-02-07 14:36:17] ERROR[4479] res_pjsip.c: Error 171060 'Unsupported transport (PJSIP_EUNSUPTRANSPORT)' sending OPTIONS request to endpoint 3351

What happens when I try to call IN to an extension:

Do you have the Reload Transports option set to Yes in FreePBX? If so ensure it is set to No, as it can cause problems (such as this) when Asterisk is reloaded.

Well, it IS currently enabled. Disabling it.

So I’ll monitor it now. Any chance you could tell me why you think this might affect it?

Thanks by the way.

The PJSIP library doesn’t have the concept of reloading or restarting transports. Instead the option mentioned enables a bruteforce approach which destroys the transports and recreating them. It suffers from a race condition, however, whereby the transport may still exist (as it is destroyed asynchronously) at the time the new one is being created. The creation of the new one fails and eventually the old one is destroyed, leaving you with no transport. Within Asterisk the option is disabled by default and is documented with a recommendation to leave it off unless absolutely necessary.
