Hello, I tried to connect my 3CX system with CUCM but without success. I created a sip trunk and it works, but with this i can only forward incoming calls from VoIP providers to CUCM but a phone from CUCM cannot call numbers via 3CX VoIP provider. So, i tried to create an 3cx bridge connection but without success. Is there anybody who did something like this? Any help will be appreciated.
