Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication apparatus which is connected to another communication apparatus via a plurality of types of communication paths and performs communication using the communication paths, a control method thereof, and a computer-readable memory.

[0002]

2. Description of the Related Art Conventionally, when communicating via a communication path such as a general public line or the Internet, a user has to know the characteristics of each communication path. For example, in the case of using the Internet, although the line usage fee is not charged unlike the general public line due to the structure of the communication path, the following precautions are required. In other words, e-mail communication via the Internet may not deliver the e-mail you want to send, it may not be possible to confirm whether the e-mail has been sent to the other party, and the contents of the e-mail may be intercepted by a third party. There is a high risk that the e-mail to be sent to the other party will take longer than communication via the public telephone network. Then, the user needs to use the Internet after fully recognizing these precautions.

[0003] In addition, in the case of communication different from the communication path of a general public line, a prerequisite is that the user is aware of what communication path to use for the communication. That is, when the communication path to be used is different, the operator is required to recognize the communication as completely different communication. Therefore, when there are a plurality of communication paths for the same destination, each destination is treated as a different destination, and a destination such as a one-touch key used in a facsimile machine or the like corresponds to one one-touch key. In the case where communication is performed by using this method, the destination numbers of the respective communication paths are registered in separate one-touch keys even though the destinations are the same.

[0004] To give a specific example, for example, if both the T office and the S office have a facsimile apparatus capable of communicating with a general public line via a LAN, the facsimile apparatus includes a facsimile apparatus via a LAN and a public network. Each destination number via the telephone line is registered with a one-touch key. Therefore, if you want to send data from T office to S office,
Since only one of the one-touch keys is used for transmission, the T office must determine in advance which communication path destination number to use to transmit data to the S office.

[0005]

However, according to the above-mentioned prior art, even though there are a plurality of destination numbers for the same destination, they are registered with different one-touch keys. There was a lot of waste in terms of bias and the effective use of a finite number of one-touch keys.
