Hello members, I have been told that the BT Home hub 5 has issues in Port forwarding 5060 to 3CX installations. I am satisfied that the Debian version of 3CX I have installed is installed correctly as I get the all green on the firewall checker, with the exception of port 5060 which keeps appearing with the error "unmatched mapping". I have tried a different modem/router (Zyxel VMG8924) and get the same error. Is this a modem / port forwarding issue and I have just been unlucky with both modems, or is it something more Sinister! I'm sure I'm not the only one to have experienced this with the BT homehub 5. Any recommendations for a substitute? Thanks in advance.
