    So I have green lights on the SIP trunk and I can make outbound calls no problem. Firewall is open on ports 5060 and 9000-9500 and came up greens lights on the firewall checker. What am I missing? I've run freepbx and elastix servers no problem so this isn't my first rodeo.

    Check the 3CX Activity logs to see if there is a sign of one of the calls. If 3CX is receiving it, then the log should show what is happening to it.

    That's because they don't know any better. Default RTP range for many Asterisk deployments is 10000-20000. 3CX is 9000-9500. But either way it's not an audio issue at this point as the SIP traffic doesn't appear to be hitting the PBX

    I would check that your port forwarding rules are pointing to the right internal destination. Also, you don't mention if you are registration or IP based authentication. But it sounds like calls aren't even hitting the PBX which would indicate either a firewall issue or routing/trunk config issue on the provider side.
