Hey Tony, I am using SIPX ver 4.0. My server has a static IP address and I do not have a stun server.
I have tested the SIPX server in the private subnet with the phones and later gave it a public IP address, with which all the phones are able to register but they cannot make calls. The firewalls used are cisco ASA 5510, some use NAT and most use PAT. The phones cannot call each other being behind the NAT or PAT is a stun server a must? If yes please suggest how I could install a STUN server on the same box where the SIPX server is installed as the SIPX server is on public IP address.
