Abstract
In order to facilitate connecting to a SIP network, a router () forming a communication system () acquires information from a carrier network () by using DHCP. The information is necessary for connecting to a server (SIP server) placed on the carrier network. Moreover, a communication device () acquires the information from the router () by using local protocol that differs from the SIP and the DHCP. For example, UPnP protocol is adopted as the local protocol.
