Not receiving calls through VOIP provider

[organetic]

Hi 3CX users. Maybe someone can help me solving this problem, and later I'll buy you a beer

3CX is not receiving calls from one of my VOIP providers.
The provider is registered, there's a green line on trunks. I can make phonecalls through this, but not receive calls.
I have tested with firewall disabled, but the problem stays the same.

This is a strange behaviour, since when I use X-Lite, everything works perfectly.

Check the 3CX logs, if you don't see an incoming call attempt, then it is probably, but not necessarily, a router/firewall issue.
