Portable communication terminal , computer program and method for originating a call

A portable communication terminal 101 is capable of originating a call based on any one of a plurality of local numbers that can be used upon origination. Previously registered in an address book 112 are each communication counterpart and a specific local number to be selected from the plurality of local numbers upon origination in association with each other.
