a call-through-LAN unit which has a function of making a call through a wireless LAN;
a call-through-telephone-network unit which has a function of making a call through a wireless telephone network; and
a call switch unit which determines a condition of communication realized by the call-through-LAN unit in response to detection of an incoming call that has arrived at the call-through-telephone-network unit via the wireless telephone network, establishes a connection through the call-through-telephone-network unit if the determined condition of communication falls outside a predetermined criterion, and establishes a connection through the call-through-LAN unit if the determined condition of communication satisfies the predetermined criterion.
