I have sipXecs 4.0.1 running behind an ASA and phones out anywhere on the Internet (behind NAT or not).
Turn off the SIP application layer gateway in the ASA and map the required ports back to the sipX box from the outside interface (UPD 5060, 30000 - 31000).

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.

Did you remove the subnets in the schema that are not part of your local network? Are any of the remote firewalls using an Application Layer Gateway on the firewall?
