DEFAULT GATEWAY, TERMINAL DEVICE, AND METHOD FOR EXCHANGING VOIP SIGNALING |
摘要 |
A terminal device receives a called telephone number inputted by a user. The terminal device generates a called domain name corresponding to the called telephone number according to a predefined rule, and queries the DDNS server for a called IP address that corresponds to the called domain name. The terminal device exchanges VoIP signaling with a called terminal device according to the called IP address when the called IP address is successfully queried from the DDNS server.
