Abstract

An image communicating apparatus capable of transmitting/receiving image data via a high-speed digital line network determines whether a transmission destination device is busy. If it is determined that the transmission destination device is busy, the image communicating apparatus redials the transmission destination device a preset number of times. If it cannot be determined that the transmission destination device is busy and transmission has not ended normally, the image communicating apparatus redials the transmission destination device by limiting a redial count.

First claim

What is claimed is:

1. A communication apparatus which is able to communicate with an external apparatus via an IP-network by a facsimile, the communication apparatus comprising:
a redial unit configured to perform either a first redial process or a second redial process, wherein the first redial process redials a maximum number of times which is predetermined to a user, and the second redial process redials once irrespective of the maximum number of times which is predetermined to the user; and
a control unit configured to control the redial unit to perform the first redial process in a case where the communication apparatus receives a SIP busy signal indicating that the external apparatus is in use or a voice packet indicating that the external apparatus is in use, and to control the redial unit to perform the second redial process in a case where the communication apparatus does not receive either the SIP busy signal or the voice packet and a time-out occurs.

2. The communication apparatus according to claim 1 , wherein the communication apparatus is a printing apparatus.

3. A communication apparatus which is able to communicate with an external apparatus via an IP-network by a facsimile, the communication apparatus comprising:
a redial unit configured to perform a redial process for redialing a maximum number of times which is predetermined to a user; and
a determination unit configured to determine whether to perform the redial process,
wherein the determination unit determines to perform the redial process in a case where the communication apparatus receives a SIP busy signal indicating that the external apparatus is in use or a voice packet indicating that the external apparatus is in use, and
wherein the determination unit determines not to perform the redial process in a case where the communication apparatus does not receive either the SIP busy signal or the voice packet and a time-out occurs.

4. The communication apparatus according to claim 3 , wherein the communication apparatus is a printing apparatus.

5. A communication method for a communication apparatus which is able to communicate with an external apparatus via an IP-network by a facsimile, the communication method comprising:
a redial step to perform either a first redial process or a second redial process, wherein the first redial process redials a maximum number of times which is predetermined to a user, and the second redial process redials once irrespective of the maximum number of times which is predetermined to the user; and
a control step to control the redial step to perform the first redial process in a case where the communication method receives a SIP busy signal indicating that the external apparatus is in use or a voice packet indicating that the external apparatus is in use, and to control the redial step to perform the second redial process in a case where the communication apparatus does not receive either the SIP busy signal or the voice packet and a time-out occurs.

6. A non-transitory computer readable medium storing a program for performing a communication method for a communication apparatus which is able to communicate with an external apparatus via an IP-network by a facsimile, the communication method comprising:
a redial step to perform either a first redial process or a second redial process, wherein the first redial process redials a maximum number of times which is predetermined to a user, and the second redial process redials once irrespective of the maximum number of times which is predetermined to the user; and
a control step to control the redial step to perform the first redial process in a case where the communication method receives a SIP busy signal indicating that the external apparatus is in use or a voice packet indicating that the external apparatus is in use, and to control the redial step to perform the second redial process in a case where the communication apparatus does not receive either the SIP busy signal or the voice packet and a time-out occurs.

7. A communication method for a communication apparatus which is able to communicate with an external apparatus via an IP-network by a facsimile, the communication method comprising:
a redial step to perform a redial process for redialing a maximum number of times which is predetermined to a user; and
a determination step to determine whether to perform the redial process,
wherein the determination step determines to perform the redial process in a case where the communication apparatus receives a SIP busy signal indicating that the external apparatus is in use or a voice packet indicating that the external apparatus is in use, and
wherein the determination step determines not to perform the redial process in a case where the communication apparatus does not receive either the SIP busy signal or the voice packet and a time-out occurs.

8. A non-transitory computer readable medium storing a program for performing a communication method for a communication apparatus which is able to communicate with an external apparatus via an IP-network by a facsimile, the communication method comprising:
a redial step to perform a redial process for redialing a maximum number of times which is predetermined to a user; and
a determination step to determine whether to perform the redial process,
wherein the determination step determines to perform the redial process in a case where the communication apparatus receives a SIP busy signal indicating that the external apparatus is in use or a voice packet indicating that the external apparatus is in use, and
wherein the determination step determines not to perform the redial process in a case where the communication apparatus does not receive either the SIP busy signal or the voice packet and a time-out occurs.
