Abstract

In a telephone switching apparatus equipped with an automatic call recording function, when recording of a call is started, a PB signal cannot be sent by operating a button any longer. Further, a user mistakenly assumes that there is a problem because the PB signal cannot be sent. Means capable of selecting, when recording means starts recording of a call, whether a PB signal is sent or not is provided, thus making it possible to send a PB signal.

First claim

The invention claimed is:

1. A telephone switching apparatus accommodating at least one extension telephone and configured to enable the extension telephone to communicate with an outside-line network through an outside-line interface, wherein
the telephone switching apparatus comprises:
at least one memory storing instructions, and
at least one processor configured to execute the instructions to;
record a call between the extension telephone and the outside-line network,
when recording of the call is started, a button operation becomes a recording function operation state where a DTMF (Dual Tone Multi-Frequency) signal cannot be sent, and
wherein the at least one processor is further configured to execute the instructions to switch, when recording of the call is started, the button operation to a DTMF signal sending function operation state where a DTMF signal can be sent in response to an operation performed at a specific button of the extension telephone.

2. The telephone switching apparatus according to claim 1 , wherein the at least one processor is further configured to execute the instructions to switch, when the extension telephone makes an outgoing outside-line call, to signal sending function operation state when a response from the outside-line network is a response from an automatic voice response apparatus.

3. The telephone switching apparatus according to claim 1 , wherein the at least one processor is further configured to execute the instructions to stop call recording and sends a DTMF signal when a button for sending the DTMF signal is operated in the extension telephone.

4. The telephone switching apparatus according to claim 1 , wherein the at least one processor is further configured to execute the instructions to stop call recording when a button for requesting to stop call recording is operated in the extension telephone.

5. A communication method for a telephone switching apparatus accommodating at least one extension telephone and configured to enable the extension telephone to communicate with an outside-line network through an outside-line interface, wherein
a call between the extension telephone and the outside-line network is automatically recorded and when recording is started, a button operation becomes a recording function operation state where a DTMF (Dual Tone Multi-Frequency) signal cannot be sent, and
the communication method comprises switching, when recording of a call is started, the button operation to a DTMF signal sending function operation state where a DTMF signal can be sent in response to an operation performed at a specific button of the extension telephone.

6. A non-transitory computer readable medium storing a program for causing a computer to perform a communication method, the method comprising:
recording a call between the extension telephone and the outside-line network automatically, wherein a button operation becomes, when recording of the call is started, a recording function operation state where a DTMF (Dual Tone Multi-Frequency) signal cannot be sent; and
switching, when recording of the call is started, the button operation to a DTMF signal sending function operation state where a DTMF signal can be sent in response to an operation performed at a specific button of the extension telephone.
