A phone terminal is provided which allows more efficient use of a record area for recording call data than before. A complex apparatus is capable of suspending recording of call data during a period in which a no-service state is detected. As a result, the recordation of call data is not performed while the call is interrupted. The call data no longer contains a voiceless area. The size of the call data can be minimized, resulting in that the effective use of the record area is promoted.
