Hi, We have a 3CX V12 with a single private IP system set up behind a NAT route. All the port forwarding is in place and we have remote extension that works perfectly but we'd like to have more and use the remote provisioning feature. http://www.3cx.com/blog/docs/provisioning-a-remote-extension/ However whenever I try to set the phone to provision I receive a pop saying:- Static Public IP Address is not specified in 3CX. This phone cannot be provisioned as an external extension, click on Settings > Network and the the Public IP Address of 3CX. Needless to say the IP address is in there.
