Communication apparatus and control method

A communication apparatus configured to execute a facsimile communication using an Error Correction Mode (ECM) function based on a facsimile procedure with a communication partner connected via an Internet Protocol (IP) network, the communication apparatus comprising:

• a transmitting unit configured to transmit, to the communication partner via the IP network, a communication start request for requesting starting the communication;
• a receiving unit configured to receive a response to the communication start request from the communication partner, the response including information that indicates whether the communication partner is capable of executing the communication using the ECM function;
• a notifying unit configured to, when the receiving unit receives the response, send to the communication partner a notification in conformance with a standard facsimile procedure, the notification indicating whether the communication apparatus executes the communication using the ECM function with the communication partner;
• and
• a determining unit configured to determine whether a transport protocol for use in the communication is a transport protocol which has an error correction function,
• wherein, if the determining unit determines that the transport protocol for use in the communication is not the transport protocol which has the error correction function, the notifying unit sends the notification to the communication partner based on whether the communication partner is capable of executing the communication using the ECM function, and if the determining unit determines that the transport protocol for use in the communication is the transport protocol which has the error correction function, the notifying unit sends the notification indicating that the communication apparatus executes the communication without using the ECM function with the communication partner to the communication partner regardless of the communication partner being capable of executing the communication using the ECM function.

A method for an apparatus operable to execute a facsimile communication using an Error Correction Mode (ECM) function based on a facsimile procedure with a communication partner connected via an Internet Protocol (IP) network, the method comprising:

• receiving, from the communication partner via the IP network, a communication start request including protocol information that indicates a transport protocol for use in the communication;
• sending to the communication partner a notification in conformance with a standard facsimile procedure when the communication start request is received, the notification indicating a capability of the apparatus;
• and
• determining, based on the protocol information, whether the transport protocol for use in the communication is a transport protocol which has an error correction function,
• wherein, if it is determined that the transport protocol for use in the communication is not the transport protocol which has the error correction function, the notification indicating that the communication apparatus is capable of executing the communication using the ECM function is sent to the communication partner, and if it is determined that the transport protocol for use in the communication is the transport protocol which has the error correction function, the notification indicating that the communication apparatus is not capable of executing the communication using the ECM function is sent to the communication partner regardless of the apparatus having the ECM function.
