JP2001352392A - Phone system incorporating automatic phone message recording function - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a phone system compatible with the ISDN incorporating an automatic phone message recording function that can carry out a reply by the automatic phone message recording function even when a master unit is busy while an automatic phone message recording mode is set. SOLUTION: In the case that a 1st channel is busy because of a speech by the master unit or reproduction of a phone message in an automatic telephone message recording mode, since this means the presence of an operator in spite of the setting of the automatic telephone message recording mode, the phone system incorporating an automatic phone message recording function rings other idle speech terminal (e.g. a cordless slave unit) without the operation by the automatic telephone message recording function when an incoming call arrives through a 2nd channel.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses two or more communication channels simultaneously, such as a telephone device that can be connected to a digital public communication line (ISDN) and a telephone device that can connect two analog public communication lines. The present invention relates to a telephone device with a built-in answering machine having a function of answering.

[0002]

2. Description of the Related Art In recent years, ISDN has spread widely,
Various communication devices connected to the Internet have been developed. On the other hand, many telephones and personal fax machines with an answering machine function have been developed.

[0003] In this flow, a communication apparatus connected to a communication line having two communication channels, such as ISDN, and having an answering machine function is disclosed in Japanese Patent Application Laid-Open No. 8-204814.

[0004]

However, the conventional I
In the answering machine with SDN, if the answering machine is set and the base unit is in use, the answering machine cannot respond. Therefore, in this case, no incoming call is made, so even if two lines are accommodated,
There is a problem that two lines cannot be used.

According to the present invention, there is provided an answering machine with built-in answering machine which can execute a response by answering machine even when the base unit is in use when the answering machine is set in the answering machine for ISDN. It is intended to do so.

[0006]

According to the present invention, in the absence mode, when the first line is in a call with the master unit or in the absence recording mode, an operator exists even in the absence mode. Therefore, when there is an incoming call from the second line, the telephone device with a built-in answering machine does not perform the operation by the answering machine, but rings another unused calling terminal (for example, a cordless handset).

And a tone output unit for creating and outputting various tone signals such as a busy tone for notifying an operator during a call.

Next, a description will be given of the operation of the above embodiment when an incoming call is received on the second line.

FIG. 3 is a flowchart showing the operation of the digital cordless processing section 222 in the above-described embodiment, and in particular, is a flowchart showing the operation when there is an incoming call on the second line.

(Operation at the time of incoming call on the second line) First, when there is an incoming call, a "call setup" message (SE
TUP) is sent through the ISDN interface unit 219. As a result, the CPU 201 determines that there is an incoming call. After obtaining the mode state information from the CPU 206, the CPU 201 determines whether or not the mode is the absence mode (S501).

If the "absent mode" is not set,
Call an unused call terminal and call the network
Sends a "call" message (ALERT).

If the facsimile apparatus body is not in use, a ringing tone is made to sound on the speaker 214, and if the PHS slave units 21 and 22 are not in use, the PHS processing unit 222
Instructs each of the PHS handsets 21 and 22 to call (S
502).

If the "absent mode" is set (S5
01), it is checked whether or not a call is being made between the parent device and the child device (S
503) If the master unit or the slave unit is engaged in a call, call a call terminal that is not being used and send a “call” message (ALERT) to the network.

If the facsimile machine main body 10 is not in use, a ringing tone is made to sound on the speaker 214 and the PHS
If the slave units 21 and 22 are not in use, the PHS processing unit 22
2 to instruct each PHS slave to call (S
502).

If the parent device is not talking, it is determined whether or not the answering machine is being reproduced by the operator (S50).
4). In this case, if the answering machine is being played, it is determined that there is an operator even in the answering machine mode, and an "call" message (ALERT) is sent to the network.

If the facsimile apparatus main body 10 is not in use, a ringing tone is made to sound on the speaker 214 and the PHS
If the slave units 21 and 22 are not in use, the PHS processing unit 22
2 instructs each PHS slave to call (S5
02).

Even during a call, unless the answering machine is playing the answering machine, it is determined whether or not the answering machine can be operated (S505). Sends a "disconnect" message (DISC) to disconnect the line (S506).

If the answering machine operation is possible (S505), the response message 1 "I'm out now. If you use it, please give me a message after the beep. FA
The answering machine / playback unit 215 sends the message to the line (S507).

Next, it is determined whether the other party is a facsimile or a person (S508). If the person is a person, an answering machine is recorded (S5).
09), when CNG is received and it is determined to be FAX,
FAX reception is performed (S510).

Thus, when there is an incoming call on the second line, the incoming call can be made on the two lines even in the absence mode.

In the above embodiment, in a communication apparatus capable of two-channel communication, when an incoming call is received during a call on one channel, the answering machine is in the answering mode. A first means for preventing incoming calls if used on a line is provided. When an incoming call is received during a call on one channel, the first mode is in the answering machine mode, and the resources required for answering machine are stored in the first means. This is an example of a telephone device with a built-in answering machine provided with a second means for not receiving a call in the answering machine mode when the first line is not being used in a line and the first line is in a call with a master unit or a slave unit. .

According to the above-described embodiment, it is possible to prevent useless incoming calls, and if the second line is received in the answering machine mode while the operator is talking on the phone, 1
The disadvantage that the line cannot be used for a voice recording / playback function such as a voice memo function can be prevented, and the second line can be received.

[0042]

According to the present invention, when an answering machine is set in an ISDN answering machine,
There is an effect that a response by answering machine can be executed even when the base unit is in use.
