Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with some processes and examples.

[0026] see figure 1 , is a structural block diagram of the short message server used in the method for calling back and establishing a call by using short messages in the present invention.

[0027] The short message server includes a PBX (Private Branch eXchange, private branch exchange) main control module and an analog interface module. The analog interface module includes a GSM (Global System for Mobile Communications, Global System for Mobile Communications) communication unit.

[0028] Among them, the PBX main control module is responsible for the voice exchange function, locates the external and internal voice calls to their destination call numbers, and is responsible for the interaction and exchange of voice signals. At the same time, it is responsibl...

Abstract

The invention provides a method for establishing communication by using a short message to call back. The method comprises the following steps: firstly, transmitting a short message to a short message server by a user; analyzing content of the short message after the short message server receives the short message, and starting a line to call back to the party transmitting the short message after the content of the short message containing specific telephone call back content and the number of the other party is confirmed; selecting another line to call the number of the other party after the party transmitting the short message is connected; and establishing the communication for two parties after the number of the other party is connected. The method for establishing the communication by using the short message to call back has the advantages that secondary dialing can be carried out through a short message mode to achieve the aim of third party communication without secondary dialing in a communicating process, save key-press in the communicating process, and reduce the opportunity of error key-press; furthermore, the calling party and the called party become called parties when telephone call back is carried out through the short message mode, thereby greatly saving communication cost.

Description

【Technical field】 [0001] The invention relates to a method for making a call, in particular to a method for calling back and establishing a call by using a short message. 【Background technique】 [0002] PBX (Private Branch eXchange, private branch exchange), that is, the telephone service network used within the company, the extension users in the system share a certain number of outside lines. PBX is a kind of telephone communication management method commonly used in modern offices, which enables telephone administrators to collectively manage external calls and internal calls. [0003] Existing PBXs usually have the function of calling back. The so-called calling back is actually that user A dials the public network number provided by the PBX system, hangs up after the system rings, and the system records the calling number A. Then, the system calls back Dial caller A, A enters the actual called number B according to the voice prompt, the system dials B, and then connect...
