Abstract
A SIP server 100 includes a first memory 20 storing a route management table in which, of route set information specified by a SIP signal on a session-by-session basis, address information as of each Record-Route header value is associated with a logical number, the same address information as of a Record-Route header values being set to the same single logical number; and a second memory 30 storing session information other than the address information as of each Record-Route header value, instance management information for use in session control, and logical numbers. The address information as of each Record-Route header value, which is stored in the first memory 20 is read on the basis of the logical numbers stored in the second memory 30.
