2. Description of the Related Art A telephone accommodated in a general public communication network is equipped with an answering machine function, and when the user is absent, the telephone is set to be in an absent state so that an answering machine function is activated at a subsequent incoming call. Automatically responds, and plays a voice message that is recorded in advance and notifies the user of absence.
2. Description of the Related Art An answering machine, which allows a caller of an incoming call to listen, records a message message to the user according to the wishes of the caller, and enables the user to listen to the message later, has been widely used.

In such a conventional answering machine, in order to send back an absent notification voice message reproduced to a caller, and to receive and record a message message sent from a caller, the answering machine responds to an incoming call. Therefore, it is necessary to set a communication path between the calling telephone and the answering machine, and a load for setting the communication path is added to the public communication network regardless of the absence of the called party.

In the public communication network, when the called telephone answers, it is determined that the call is a charging target call, and the charging process for the normal caller is started. The call charge will be collected even if the call is not made.

Japanese Unexamined Patent Publication No. Hei 1-10151 (1992)
The invention “Digital Answering Machine”, which was released on the 19th of March, seems to solve such a problem. The invention "digital answering machine" is intended for an answering machine accommodated in an integrated service digital network (ISDN). By returning a message for absentee notification using user / user information when a missed call is received. , It is not necessary to respond and seize the line.

However, the above-mentioned invention "digital answering machine"
In order to receive and record the voice message for the message sent by the caller on the answering machine, it is necessary to set the call path between the calling phone and the answering machine. The problem of adding load to the public network and charging the originating telephone has not been completely solved.

Further, when the conventional answering machine is set to be in the absence state, the answering machine function is executed uniformly for all incoming calls, and the execution of the answering machine function is distinguished for each caller or is absent. Performing different answering machines depending on the called party was not considered.

Further, in the conventional answering machine, in order to be able to execute the answering machine function, the user needs to perform the designation operation and the designation cancellation operation each time. However, in some fields of use of answering machines, it is predetermined that the user will be absent at certain times of the day, or will be absent on a specific day of the week or on a specific month. In addition, each user needs to execute the operation for specifying and canceling the specification of the answering machine function, and if he / she inadvertently forgets the specifying operation, the desired answering machine function cannot be executed.

Further, in the conventional answering machine, when the user who listens to the recorded voice message for message wants to talk directly with the caller, he or she hears the telephone number from the voice message for message, or Alternatively, the telephone number is searched after listening to the name of the sender, and the outgoing call is connected to the message sender by the obtained telephone number.

[0010]

As is clear from the above description, the conventional answering machine has the following problems.

That is, first, in order to return a voice message for absentee notification to an incoming call that is absent and to receive and record a message for a message transmitted from a missed callee, the missed call is called. Since it is necessary to respond to the call and set up a communication path with the calling telephone, an extra load is added to the communication network for setting the communication path, and even though the requirement is not achieved, it is charged There was a problem that the call charge was collected as a call.

Secondly, if the answering machine function is designated, the uniform answering machine function is executed for all incoming calls, and the execution of the answering machine function is distinguished depending on the missed callee, or the missed call reception is performed. There was a problem that it was not possible to execute different answering machines depending on the person.

Third, when designating and canceling the designation of the answering machine function, the user needs to execute the designation operation and the designation canceling operation of the answering machine function on the answering machine each time, which requires a lot of trouble for the user. There was a problem hanging.

Fourthly, in order to make an outgoing connection to the message sender who sent the message message, the user listens to the message message, listens to the telephone number or name of the message sender,
When the name is heard, it is necessary to search the telephone number further, which causes a great burden on the user.

An object of the present invention is to solve each of the conventional problems as described above and to greatly improve the convenience for the user of the answering machine.
