Patent ID: 7813269

Claim:
A communication apparatus which starts based on a program stored in a first recording medium to execute communication processing, comprising: an acquisition module configured to selectively acquire equipment information showing communication equipment including the same program as the program recorded on the first recording medium to record the equipment information in a second recording medium differing from the first recording medium from a communication partner, in communicating with the communication partner; and a failure restoration module configured to obtain a program from communication equipment based on the equipment information recorded on the second recording medium, and start the communication apparatus based on the obtained program, when the communication apparatus cannot start by the program recorded on the first recording medium, wherein the acquisition module determines whether or not a program version of the communication partner is the same as a program recorded in the first recording medium based on the equipment information acquired from the communication partner, and automatically records the equipment information of the communication partner as a program acquisition destination candidate on the second recording medium, when the program versions are equal to each other.
