Abstract: The invention is to enable a secure sharing of an internet resource with a partner in conversation by the IP telephone, in simple and inexpensive manner and not requiring cumbersome operations, by a communication terminal only, not relying on another equipment. Internet resource sharing means is provided for a shared utilization of a same internet resource (WEB data, FTP file etc.) among the communication terminals (200, 220) in conversation. The sharing of the internet resource is executed by transmitting/receiving URL information of the desired internet resource by FTP or by an E-mail protocol, or by transmitting/receiving the internet resource itself by an HTTP proxy procedure with the partner communication terminal, in which either of the communication terminal and the partner terminal functions as an HTTP proxy server and the other functions as an HTTP client.

A CPU of the data communication apparatus combines a page number allotted to each of the images converted into files with the subject of the electronic mail that is inputted, to generate an attached image file name, and transmits the electronic mail with the image data in the form of files attached thereto together with the generated attached image file names. Therefore, it is not necessary to input the name of an image file attached to an electronic mail, which facilitates the operation of transmitting an electronic mail and enables giving a file name that enables the receiver of the electronic mail to easily recognize the contents of the attached image file.

The URL information of an Internet resource is registered to a one-touch key. Registering the selection information of the communication terminal of the other party and the URL information of an Internet resource enables the URL information thereof to be transferred to the communication terminal of the other party with which the phone conversation has been established immediately following calling the other party by pressing the one-touch key, so as to allow the browser of the communication terminal of the other party to browse the Internet resource. Thus, both the calling and receiving parties can browse the same Internet resource with the respective terminals.

Abstract: A communication apparatus which performs IP communication and analog communication through an ADSL gateway obtains an IP address of a party station from an SIP proxy and transmits/receives communication data with the party station on an IP network based on a file transmission/reception protocol such as FTP or HTTP when a party station's telephone number corresponds to a VoIP network. The apparatus performs analog facsimile communication on a line switching network when the party station does not correspond to the VoIP network. Moreover, the apparatus performs the analog facsimile communication on the VoIP network or the line switching network when the party station corresponds to the VoIP network but does not have any digital communication means. Thus, in the apparatus corresponding to analog and network communication paths, it is possible to select an appropriate communication path and achieve high-speed and high-reliability communication without any complicated operation.
