Abstract

PROBLEM TO BE SOLVED: To prevent generation of the waste of communication costs and to prevent an other party from feeling uncomfortable by judging matching of the functions including terminal classification of a terminal being the origin of transmission and a terminal being the destination of transmission at the time of transmission, operating transmission when the mutual functions mach, and operating transmission control when they do not match. SOLUTION: A main controller 102 detects a call signal from an analog general telephone set 104, moves to a call processing, and operates the confirming processing of a terminal classification ID. At the time of the terminal classification ID confirming processing, the terminal classification ID of the telephone number of another side terminal classification ID table is compared with the terminal classification ID of the transmitting terminal so that whether or not any common function is present can be judged. When the terminal classification ID confirmation is OK, the main controller 102 moves to a normal speech processing. When the terminal classification ID confirmation is NG, the main controller 102 transmits an alarm signal to the analog general telephone set 104, and transmits a disconnection signal to a communication network 101, and oeprates a series of disconnection processing.

If the terminal type ID confirmation is OK, the main unit 102 sends a hooking signal 1506 to the network via the PSTN interface 201 (S1921).
After that, dial signals 1507-1 to 1507-N are transmitted based on the stored dial information (S1922),
The process shifts to a normal busy process (not shown).

When the terminal type ID confirmation is NG, as shown in FIG. 17, the main device 102 sends a warning signal 1606 via the SLT interface 205 (S
1906), a disconnection signal 1607 is transmitted via the PSTN interface 202, and a series of disconnection processing for transmitting a release signal 1609 to the PSTN by the disconnection signal 608 from the G3 FAX 107 is performed (S1907), and a warning message process shown in FIG. Move to.

In the warning message processing of this embodiment, when it is determined that there is a warning message (YE in S2001).
S), based on preset data, to one or more terminals in the vicinity of the originating terminal (G3FAX) or a preset specific terminal whose terminal type ID is set to voice communication. Incoming signal 70 with special ringtone
1 is transmitted (S2002).

In response to this incoming call, the analog ordinary telephone 10
4, a response signal 702 is transmitted, and the main device 102 receives it (S2004), stops the incoming signal (S2005), and then issues a warning message 1703.
Is generated and transmitted by the main device voice synthesis unit 206 (S200).
6) Then, a disconnection process for waiting for a disconnection signal 1704 due to on-hook is performed (S2007), and the process returns to the idle process.

As the warning message 1703, a message with a reason for restricting the transmission, such as "cannot make a call because the terminal type is different," or "cannot make a fax because the other terminal is a telephone" is given. Used. As a result, the caller can know that the transmission has been restricted and the reason therefor.

In the above embodiment, the method of notifying the transmission restriction by a voice warning message has been described, but the notification may be similarly notified by a communication result report.

This is because the main unit 102 is provided with a function of creating report data, and when the above-mentioned transmission restriction is performed,
Create a report stating that transmission was regulated and why. Then, an incoming call is processed to the data terminal or the extension terminal having a printer function such as a facsimile which has performed the calling operation, and the report data is transmitted after the response, so that the extension terminal prints out the report.

In the above example, the warning message is sent to a preset terminal other than the calling terminal.
When the calling terminal is a data terminal or a facsimile, it is possible to directly alert the calling terminal by the above-described report. However, in the case of transmission by reservation, etc., the caller is often not in the vicinity of the transmission terminal, so that it may be more effective to warn using a nearby telephone or the like.

In the data terminal or the like, a window is displayed on the display unit by creating and sending display data to the personal computer or the like indicating the above-mentioned transmission restriction and the reason. It is also possible.
