PURPOSE:To listen to a business message of a caller with a remote operation from a visited place by the user, by providing a function that whether or not a business message of a caller exists on a business message tape can be discriminated with the number of rings and the number of rings for the discrimination can be varied. CONSTITUTION:An incoming call from a line is detected at an incoming call detecting section 1 and the incoming call is finished by activating an incoming call relay 3 and a switch 4. When an incoming call is received with a switch 7 turned off, if no business message is recorded, the set enters the response state after three rings and if the message is recorded, the set enters the state with one ring. On the other hand, when the switch 7 is closed, the number of rings from the incoming call to the response for no business message recorded can arbitrarily be set from one to five rings by adjusting an incoming time adjuster 6. |
