Abstract
A network device is configured to receive a registration message from a private user device including a private internet protocol (IP) address associated with the private user device. A public IP address and discrete port number are assigned to the private user device and private IP address and stored in an incoming call table. The registration message is translated to include the public IP address and discrete port number. The registration message is forwarded to a proxy server for registration. An incoming call invitation message is received from a public user device, where the call invitation message is directed to the public IP address and discrete port number associated with the private user device. The call invitation message is translated to include the private IP address associated with the private user device based on the received public IP address and discrete port number and the incoming call table. The call invitation message is forwarded to the private user device.
