Method for realizing selective answering function of common telephone terminal

Abstract

The method comprises: 1) calling side calls the called side; the called side is off hook and reports the off-hook signals; the switch connects the pre-saved prompt voice to the uplink time-slot of calling side, and connects the downlink time-slot of calling side to the uplink time-slot of called side; 2) according to prompt voice, the calling side makes relevant response; 3) after receiving the response from calling side, the called side decide if the call will be answered; if yes, then based on an operation on the key of telephone terminal pre-agreed on, prompting the switch to make the call; if not, the called side can directly select a hang-up.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for realizing the function of selecting an incoming call for an ordinary telephone terminal. Background technique [0002] At present, new services emerge in an endless stream in the field of communication, but due to the limitation of fixed telephone network communication equipment technology and the limitation of terminal user functions, the realization of many new services becomes very difficult. Among them, currently only the mobile phone terminal has the service of freely choosing to answer incoming calls, while the fixed phone terminal does not have this function. In an office where many people use the same phone, it is even more important to selectively answer incoming calls. In addition, in some occasions, the user does not want to connect the phone immediately, and hopes to contact later. At this time, the mobile phone terminal can directly choose to hang...

Problems solved by technology

[0005] The above two methods have the following disadvantages: Although the first method adopts software, it can selectively answer incoming calls, but this choice must be preset before the incoming call, and this setting is for It is set for the number, not for the caller, and it cannot intelligently answer the caller selectively

Method 2 adopts the method of adding hardware, which can also selectively answer incoming calls, but the current existing terminals need to be modified or updated, and it can only be effective for one terminal. When multiple terminals need to have this function, it is necessary to It is necessary to add corresponding equipment to each terminal or replace it with a new terminal with this function
