Estimating the term…
In a communication apparatus corresponding to a voice-band analog communication path and a network communication path, high-speed and high-reliability data communication is achieved by selecting the appropriate communication path without any complicated user operation. The communication apparatus which performs IP communication and analog communication through an ADSL gateway obtains a communication partner IP address from an SIP proxy when a communication partner telephone number corresponds to a VoIP network, and transmits/receives communication data to/from the communication partner on an IP network based on a file transmission/reception protocol such as FTP, HTTP, or the like. The communication apparatus performs analog facsimile communication on a line switching network when the communication partner telephone number does not correspond to the VoIP network, and performs the analog facsimile communication when the communication partner corresponds to the VoIP network but does not have any digital communication means.
A communication apparatus which has IP (Internet Protocol) communication means and transmits/receives communication data to/from a communication partner station discriminated by a telephone number, comprising:
(canceled)
A communication system which includes a communication apparatus having IP (Internet Protocol) communication means and transmitting/receiving communication data to/from a communication partner station discriminated by a telephone number, comprising:
A control method of a communication apparatus having an IP communication means and transmitting/receiving communication data to/from a communication partner station discriminated by a telephone number, said method comprising:
(canceled)
A control program for a communication apparatus having an IP communication means and transmitting/receiving communication data to/from a communication partner station discriminated by a telephone number, said method comprising:
(canceled)
A gateway apparatus which includes IP communication means, transmits/receives communication data to/from a first partner station, and transmits/receives communication data to/from a second partner station according to a facsimile procedure, comprising:
A control method of a gateway apparatus including an IP communication means, transmitting/receiving communication data to/from a first partner station by using the IP communication means, and transmitting/receiving communication data to/from a second partner station according to a facsimile procedure by using the IP communication means, said method comprising:
A control program of a gateway apparatus including an IP communication means, transmitting/receiving communication data to/from a first partner station by using the IP communication means, and transmitting/receiving communication data to/from a second partner station according to a facsimile procedure by using the IP communication means, said program consisting of:
A communication method of, by using an IP communication means, transmitting/receiving communication data to/from a first partner station, and transmitting/receiving communication data to/from a second partner station according to a facsimile procedure, said method comprising:
