LOCAL TERMINAL DEVICE AND METHOD FOR EXCHANGING VOIP SIGNALING
First Claim
1. A local terminal device in electronic communication with a dynamic domain name service (DDNS) server and a remote terminal device via a voice over Internet protocol (VoIP) network, the local terminal device having a local Internet protocol (IP) address, the remote terminal device having a remote IP address, the local terminal device comprising:
- a user interface operable to receive a local mail address of a local user and a remote mail address of a remote user;
at least one processor;
a storage system to store one or more programs executable by the at least one processor, the one or more programs comprising;
a registration module operable to convert the local mail address into a local domain name, and transmit the local domain name and the local IP address to the DDNS server to register with the DDNS server;
a querying module operable to convert the remote mail address into a remote domain name, and query the DDNS server for the remote IP address corresponding to the remote domain name; and
a signaling exchanging module operable to exchange VoIP signaling with the remote terminal device according to the remote IP address.

Abstract
A local terminal device receives a local mail address of a local user, and converts the local mail address into a local domain name. The local terminal device transmits the local domain name and a local Internet protocol (IP) address to a dynamic domain name serve (DDNS) server to register with the DDNS server. The local terminal device receives a remote mail address of a remote user, and converts the remote mail address into a remote domain name. The local terminal device queries the DDNS server for a remote IP address corresponding to the remote domain name. The local terminal device exchanges VoIP signaling with a remote terminal device according to the remote IP address.
