Trunk context is not being assigned

My Box start working fine, but after some hours running I always have to reset (aportal restart) asterisk in my box because the call from my trunk (which context=from-trunk) do not recognize the SIP inbound call (entering in the box as from-sip-extern).

Log lines:

Inbound is also Ok, otherwise it would not start working fine.
Could someone send me an idea to solve instability of the system? I have no clue of what is happening.

Are you sure the “host=” setting matches the IP this call is coming from?

Here’s the issue, it has nothing to do with context: Rejecting unknown SIP connection from 201.86.XXX.XXX

You might want to change from “type=peer” to “type=friend”.

I tried to set the host the IP address, but when I do it, the trunk stop working no only with income calls, but also outcome calls. It just work when host=my provider domain (not IP).
