You seem to have a lot of Unknown Peer and unknown port 5060.
this is odd,
I am not sure what part is what.!
Got a call from the sip trunk but it is unknown.
Check the config for some errors.
DROP THE :5060 from the end of the IP.
This the default anyway.
This may tie in with the port disallowed :5060.
It sounds like from their website they prefer you to use their phone as I could not find any easy to follow setup assistance, so you may find the port is different or they have clever stuff detecting the “endpoint”. But if you can call the number and the call is attempted then it can only be some minor tweaking before you get a result.
Sorry I am not able to pinpoint the issue.
But happy to try and work thru it until someone drops in with THE answer…
Have a look at the Sip Chan and Registration status in Asterisk Info page.
