I am totally new to Voip. I started palying with it today. I installed the server and setup two extensions and register my voip line. I also configured digital receptionist which is working fine. Whenever somebody calls me on my extension, it rings ( I am using softphone). I can not hear them and they can not hear me. But if I call somebody or the same number from my extension, then we can hear each other. I behind NAT and I disabled firewals on both computers (server/workstation) to check if thats the problem. If somebody help me to resolve this issue please. Thanks in advance.
