Abstract
A communication apparatus capable of executing facsimile transmission in any of real-time Internet mode and VoIP-based virtual voice mode and capable of switching voice communication to facsimile communication of the real-time Internet mode which is higher in communication speed than the virtual voice mode. In a case where voice communication is switched to facsimile communication, the facsimile transmission is executed in T.38 mode, if it is determined based on destination information stored in a storage unit of the communication apparatus that a communication destination with which the voice communication is being performed is capable of performing facsimile communication in T.38 mode.
Claims9
A communication apparatus capable of performing first facsimile communication using a real-time Internet mode in which image data is transferred through IP packets and second facsimile communication using a VoIP-based virtual voice mode, comprising:
- a storage unit configured to store at least one piece of destination information each representing whether a corresponding one of at least one pre-registered communication destination is capable of performing the first facsimile communication;
- a voice communication unit configured to perform VoIP-based voice communication with a communication destination by establishing a call connection;
- and
- a transmission unit configured, in a case where the voice communication is switched to facsimile communication while the call connection is being established, to perform the first facsimile communication to transmit image data, if it is determined based on the at least one piece of the destination information stored in said storage unit that a destination of the voice communication is capable of performing the first facsimile communication.
A control method for a communication apparatus that is capable of performing first facsimile communication using a real-time Internet mode in which image data is transferred through IP packets and second facsimile communication using a VoIP-based virtual voice mode and that includes a storage unit configured to store at least one piece of destination information each representing whether a corresponding one of at least one pre-registered communication destination is capable of performing the first facsimile communication, comprising:
- performing VoIP-based voice communication with a communication destination by establishing a call connection;
- and
- performing, in a case where the voice communication is switched to facsimile transmission while the call connection is being established, the first facsimile communication, if it is determined based on the at least one piece of the destination information stored in the storage unit that a destination of the voice communication is capable of performing the first facsimile communication.
A non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method for a communication apparatus that is capable of performing first facsimile communication using a real-time Internet mode in which image data is transferred through IP packets and second facsimile communication using a VoIP-based virtual voice mode and that includes a storage unit configured to store at least one piece of destination information each representing whether a corresponding one of at least one pre-registered communication destination is capable of performing the first facsimile communication, comprising:
- performing VoIP-based voice communication with a communication destination by establishing a call connection;
- and
- performing, in a case where the voice communication is switched to facsimile transmission while the call connection is being established, the first facsimile communication, if it is determined based on the at least one piece of the destination information stored in the storage unit that a destination of the voice communication is capable of performing the first facsimile communication.
