I have an Atcom AT-610 IP phone and a softphone connected to a 3CX server which is running on an external network over the internet. Both phones are setup correctly with the 3CX server. When I dial the softphone from the IP Phone, the softphone rings, and can hear me however I cannot hear audio from the softphone. However, when dialing the IP Phone from the softphone, it does not ring at all. In the server logs, I noticed that the softphone is trying to connect to the local IP of the IP Phone (192.168.0.10) from the 3CX server, which is obviously never going to work as the 3CX server is on another network and I'm accessing it over the interent. I have 3 softphones configured that all work fine, it is just this hardware IP Phone that has the problem. I suspect that this is something to do with the phone configuration, can anyone reccomend something for me to try?
