IP fax and its work method

Abstract

An IP fax and working method thereof, referring to the technical field of utilizing IP technique to fax. This invention includes a mail sending / receiving module, a session initialization protocol fax device, opposite user agents, further includes an IP fax server; a control order port of the mail sending / receiving module is connected with the IP fax server; after receiving by IP fax server, the IP fax server will send a feedback information to the mail sending / receiving module; the first input end of the IP fax server is connected with an input end of the session initialization protocol fax device so as to realize the inter-conversion flowing from T.38 to the fax file form; the second input end of the IP fax server is connected with an input end of the opposite user agents so as to realize the encapsulation to the session initialization protocol stack. The target of this invention is to provide a target of source file fax transmission which has distinct gradation, simple protocol, powerful function, supports multi-path fax session, fax file distributing mailbox and plural file forms.

Description

technical field [0001] The invention relates to the technical field of facsimile by using IP technology. Background technique [0002] At present, PBX (Private Branch Exchange) is widely used in enterprise offices, and plays an important role in improving the efficiency of enterprises. However, the traditional PBX adopts a special technology lacking openness and standardization, which is not only expensive, but also does not support the emerging CTI (Computer and Telephone Integration) and VOIP technology. In recent years, with the popularity of the Internet and the success of IP technology, IP-PBX based on IP protocol has emerged, which is expected to solve the shortcomings of traditional PBX. [0003] The IP-PBX system realizes the integration of the functions of the computer network and the telephone exchange. Each telephone terminal in the IP-PBX network system adopts IP mode for data communication, which can not only make calls, but also realize the transmission of te...

Problems solved by technology

[0007] Due to the complexity of the H.323 standard, it is too complex or expensive for many products requiring only basic "fast but not perfect" call control between network gateways

Moreover, H.323 cannot be integrated with SS7 (Signaling System #7, No. 7 signaling), or supplement the powerful functions that SS7 must provide
