Abstract:
1. A communication apparatus capable of executing facsimile communication with a communication partner connected thereto via an IP network, using an ECM function based on a facsimile procedure, comprising: receiving means for receiving a communication start request from the communication partner, the communication start request including protocol information that indicates a transport protocol used in the facsimile communication; notifying means for notifying, when the receiving means receives the communication start request, the communication partner of a capability of the communication apparatus by transmitting a DIS signal complying with a standard facsimile procedure; and determining means for determining, based on the protocol information, whether the transport protocol used in the facsimile communication is a transport protocol having an error correction function, wherein when the determining means determines that the transport protocol used in the facsimile communication is not a transport protocol having an error correction function, the notifying means transmits a DIS signal indicating that the communication apparatus has an ECM function, and when the determining means determines that the transport protocol used in the facsimile communication is a transport protocol having an error correction function, the notifying means transmits a DIS signal indicating that the communication apparatus does not have an ECM function.
