Communication management device, communication management method, communication management program, and communication management system

A communication management method for a communication management device that is connected between a mobile phone terminal connected to an external telephone terminal and an extension telephone terminal, and that causes the external telephone terminal and the extension telephone terminal to perform a call with each other via the mobile phone terminal, the communication management method comprising:

• an incoming call control step of transmitting an extension incoming call instruction to the extension telephone terminal to cause the extension telephone terminal to perform incoming call processing in response to an external call request transmitted from the external telephone terminal being input to the mobile phone terminal to input a mobile incoming call instruction transmitted from the mobile phone terminal, and based on an incoming call response instruction transmitted from the extension telephone terminal, transmitting the incoming call response instruction to the mobile phone terminal;
• an outgoing call control step of causing the mobile phone terminal to perform call-requesting outgoing call processing for the external telephone terminal based on an extension call request transmitted from the extension telephone terminal, and transmitting an extension outgoing call response instruction to the extension telephone terminal in response to an external outgoing call response transmitted from the external telephone terminal being input to the mobile phone terminal to input a mobile outgoing call response instruction transmitted from the mobile phone terminal;
• and
• a communication control step of performing voice communication control between the external telephone terminal and the extension telephone terminal via the mobile phone terminal by causing a voice information conversion unit to convert mobile voice information and extension voice information into each other in response to a call connection between the external telephone terminal and the extension telephone terminal being established in the incoming call control step or the outgoing call control step.

A non-transitory computer readable medium storing a communication management program for causing, when executed by a communication management device that is connected between a mobile phone terminal connected to an external telephone terminal and an extension telephone terminal, and that causes the external telephone terminal and the extension telephone terminal to perform a call with each other via the mobile phone terminal, the communication management device to execute:

• an incoming call control step of transmitting an extension incoming call instruction to the extension telephone terminal to cause the extension telephone terminal to perform incoming call processing in response to an external call request transmitted from the external telephone terminal being input to the mobile phone terminal to input a mobile incoming call instruction transmitted from the mobile phone terminal, and based on an incoming call response instruction transmitted from the extension telephone terminal, transmitting the incoming call response instruction to the mobile phone terminal;
• an outgoing call control step of causing the mobile phone terminal to perform call-requesting outgoing call processing for the external telephone terminal based on an extension call request transmitted from the extension telephone terminal, and transmitting an extension outgoing call response instruction to the extension telephone terminal in response to an external outgoing call response transmitted from the external telephone terminal being input to the mobile phone terminal to input a mobile outgoing call response instruction transmitted from the mobile phone terminal;
• and
• a communication control step of performing voice communication control between the external telephone terminal and the extension telephone terminal via the mobile phone terminal by causing a voice information conversion unit to convert mobile voice information and extension voice information into each other in response to a call connection between the external telephone terminal and the extension telephone terminal being established in the incoming call control step or the outgoing call control step.

A communication management system comprising:

• a communication management device configured to be connected to a mobile phone terminal that communicates with an external telephone terminal;
• and
• a communication management server configured to be connected between the communication management device and an extension telephone terminal,
• the communication management system configured to cause the external telephone terminal and the extension telephone terminal to perform a call with each other via the mobile phone terminal,
• the communication management device comprising:
• an incoming call control unit configured to
• transmit an extension incoming call instruction to the communication management server in response to an external call request transmitted from the external telephone terminal being input to the mobile phone terminal to input a mobile incoming call instruction transmitted from the mobile phone terminal, and
• transmit an incoming call response instruction transmitted from an extension incoming call control unit of the communication management server to the mobile phone terminal in response to the incoming call response instruction being input;
• an outgoing call control unit configured to
• cause the mobile phone terminal to perform call-requesting outgoing call processing for the external telephone terminal in response to a call-requesting outgoing call instruction transmitted from an extension outgoing call control unit of the communication management server being input, and
• transmit an extension outgoing call response instruction to the communication management server in response to an external outgoing call response transmitted from the external telephone terminal being input to the mobile phone terminal to input a mobile outgoing call response instruction transmitted from the mobile phone terminal;
• a voice information conversion unit configured to convert mobile voice information in the mobile phone terminal and extension voice information in the extension telephone terminal into each other;
• and
• a communication control unit configured to perform voice communication control between the mobile phone terminal and the communication management server by causing the voice information conversion unit to convert the mobile voice information and the extension voice information into each other in response to the incoming call control unit or the outgoing call control unit establishing a call connection between the external telephone terminal and the extension telephone terminal,
• the communication management server comprising:
• the extension incoming call control unit configured to
• transmit the extension incoming call instruction transmitted from the incoming call control unit to the extension telephone terminal to cause the extension telephone terminal to perform incoming call processing in response to the extension incoming call instruction being input, and
• transmit the incoming call response instruction transmitted from the extension telephone terminal to the communication management device in response to the incoming call response instruction being input;
• the extension outgoing call control unit configured to
• transmit the call-requesting outgoing call instruction to the communication management device in response to an extension call request transmitted from the extension telephone terminal being input, and
• transmit the extension outgoing call response instruction transmitted from the outgoing call control unit to the extension telephone terminal in response to the extension outgoing call response instruction being input;
• and
• an extension communication control unit configured to perform voice communication control between the communication management device and the extension telephone terminal in response to the extension incoming call control unit or the extension outgoing call control unit establishing a call connection between the external telephone terminal and the extension telephone terminal.
