To solve a problem of a conventional reception job execution system that loses general versatility because a reception job execution application software program is restricted/limited by many setting items not needed for a user side resulting in causing difficultly in location of a fault in the case that the initial setting items (reception job setting by each recipient ID, a dial-in number information table by each reception job, a caller number information table being customer information and system environment setting) is mixed or fused with the software program.

A reception job setting module 1 is designed as a separate module from a reception job execution application software program 2 for a private branch of electronic exchange 7 and an input output terminal 6 so as to limit number of initial setting items being core items to a necessity minimum. General versatility is provided to this execution module 1 by generating it by a general database and in a general language and the reliability and the quality of the reception job execution system can be enhanced by clearly separating the environment setting (initial setting item) function from the reception job function.
