Solved Error 603

[jjoshua]

I'm setting up a new install with some older phones that aren't supported so I'm jumping through some extra hoops to get things working.

My phones are registering and showing up in the phones section. However, when I attempt to call any extension, I receive error 603.

Is there some log that I can easily check to see what's going wrong?

Any ideas?

Thanks.

Ok... So the problem was that the default setting for Network / FQDN / Local Sip Domain wasn't correct.

The devices were registering with a value that 3cx wasn't expecting so 3cx just disregarded it.
