[Penthalaz3cx]

I'm getting into uncharted territory (and unsupported as we know) BUT aving the right firmware i was able to gain access to the two menus below




'im sure 'im close but i canot seem to make it work... Surely Audiocodes would not have put this option there on no grounds.. no clear info in their generic sip FW doc... could anyoone help ?

Some devices that I've used, have required both the server, and proxy port to be enabled, and both should probably be 5060. You don't say if you are using the phone on a locally, or remotely hosted setup. I have to assume remotely, as you are using an FQDN.

Check the 3CX Activity log, to see if the set is attempting to register. Until you see that, then you know that the set is not even reaching the PBX.
