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.
