Hello, I have successfully configured both the VOIP Client, and a Polycom phone to work in our internal network. We have about 15 external IP's, so I moved the 3cx system to a seperate IP and firewall. I opened the necessary ports in the firewall, and can successfully make calls from the VOIP client provided by 3CX. But for unknown reasons, I cannot get the Polycom to work remotely. All the settings have been updated, to the new public IP, but still does not work. Any suggestions? I am using a Netgear ProSafe FVX538. Thanks.
