I have a problem with TLS certificate change and, especially, automated renewal. How to make Asterisk reload the certificate with minimal service disruption?

Asterisk (PJSIP) doesn’t seem to detect certificate changes on its own. It won’t normally reload transport settings either, unless it is explicitly allowed, but event then, it probably won’t detect any changes when only certificate file contents changes, so reloading pjsip won’t help even when the certificate is changed.

The only option left is to restart whole Asterisk, which is quite disruptive.

Is there any other way?
