The Fast SIP Registration Method Using MAC Address in VoIP System

In this paper, the authors propose the SIP Registration method using MAC address in VoIP system. In the process of registering from SIP terminal to the SIP server, the SIP server requests the MAC address of the terminal and uses the method of storing the MAC address which matches with the SIP terminal. So, if the terminal is initialized or the IP address of the terminal was changed by a user movement, the SIP terminal can be rapidly registered in the SIP server by using the stored MAC address.
