Hi!
I have TrixBox 2.8.0.4 with SIP trunks (for incoming calls from provider) with IAX trunk for outgoing calls and extensions (SIP phones like LynkSys and D-Link).
Everything works fine until Asterisk server of our provider is having problems (for example is unreachable or down).
In this case of course we can't make outgoing calls and receive incoming calls, but we also unable to make internal calls!
In IAX trunk we add "unmonitored" but it doesn't help.

Can someone help me: what to configure to have at least internals call even when our provider is down?

Thank you in advance for your support!

Regards.
