Abstract
Control means of an exchange comprising connection means for accommodating a telephone and the control means for controlling the accommodated telephone, receives a dial signal from the telephone without causing the telephone to respond to an incoming call when the telephone that is performing incoming call ringing is hooked off, causes the hooked-off telephone to respond to the incoming call when the received dial signal is a first dial signal, and causes the telephone as a call source to make a call without causing the hooked-off telephone to respond to the incoming call when the received dial signal is a second dial signal. Thereby, it is possible to make a call even during incoming call ringing.

An exchange comprising:
- connection unit that is implemented at least by hardware, including a processor and memory, and that accommodates a telephone;
- and
- control unit that is implemented at least by hardware, including a processor and memory, and that controls the accommodated telephone,
- wherein the control unit
- causes some telephones of the accommodated telephones to perform incoming call ringing and does not allow other telephones of the accommodated telephones to perform the incoming call ringing when there is an incoming call, and
- varies a dial tone outputted to the telephone when the telephone that is performing the incoming call ringing is hooked off, and a dial tone outputted to the telephone when the telephone that does not perform the incoming call ringing is hooked off,
- receives a dial signal from the telephone without causing the telephone to respond to the incoming call when the telephone that is performing incoming call ringing is hooked off,
- causes the hooked-off telephone to respond to the incoming call when the received dial signal is a first dial signal, and
- causes the telephone as a call source to make a call without causing the hooked-off telephone to respond to the incoming call when the received dial signal is a second dial signal.
A call facilitation method performed by an exchange, the exchange comprising connection unit that is implemented at least by hardware, including a processor and memory, and that accommodates a telephone and control unit that is implemented at least by hardware, including a processor and memory, and that controls the accommodated telephone, the call facilitation method comprising:
- at the control unit,
- causing some telephones of the accommodated telephones to perform incoming call ringing and does not allow other telephones of the accommodated telephones to perform the incoming call ringing when there is an incoming call, and
- varying a dial tone outputted to the telephone when the telephone that is performing the incoming call ringing is hooked off, and a dial tone outputted to the telephone when the telephone that does not perform the incoming call ringing is hooked off,
- receiving a dial signal from the telephone without causing the telephone to respond to the incoming call when the telephone that is performing incoming call ringing is hooked off,
- causing the hooked-off telephone to respond to the incoming call when the received dial signal is a first dial signal, and
- causing the telephone as a call source to make a call without causing the hooked-off telephone to respond to the incoming call when the received dial signal is a second dial signal.
A non-transitory computer-readable medium having stored thereon a call facilitation program causing a computer to function as an exchange, the computer comprising connection unit that is implemented at least by hardware, including a processor and memory, and that accommodates a telephone and control unit that is implemented at least by hardware, including a processor and memory, and that controls the accommodated telephone,
- the call facilitation program causing the control unit as control unit that for
- causes some telephones of the accommodated telephones to perform incoming call ringing and does not allow other telephones of the accommodated telephones to perform the incoming call ringing when there is an incoming call, and
- varies a dial tone outputted to the telephone when the telephone that is performing the incoming call ringing is hooked off, and a dial tone outputted to the telephone when the telephone that does not perform the incoming call ringing is hooked off,
- receives a dial signal from the telephone without causing the telephone to respond to the incoming call when the telephone that is performing incoming call ringing is hooked off,
- causes the hooked-off telephone to respond to the incoming call when the received dial signal is a first dial signal, and
- causes the telephone as a call source to make a call without causing the hooked-off telephone to respond to the incoming call when the received dial signal is a second dial signal.
