Problems solved by technology

[0003] In the prior art, on the basis of unified communication and unified number, the user can answer the call through the SIP intelligent terminal, and complete control operations such as call hold, recovery, and transfer of the terminal's voice channel; the user can also use the unified number to hide the call. However, due to the inherent limitations of ordinary telephone terminals, users who can use call control functions such as hold, resume, and transfer on SIP smart terminals will not be able to continue Use or difficulty to use these functions, which brings great inconvenience to users

Embodiment Construction

[0037] The method, system and equipment described in the embodiment of the present invention will be described in detail below in conjunction with accompanying drawings 1 to 6 .

[0038] Firstly, the method described in the embodiment of the present invention will be described in detail with reference to FIG. 1 .

[0039] The method described in the embodiment of the present invention is applied to when the calling user dials a unified number and the first terminal answers the incoming call of the unified number, the second terminal controls the first terminal to transfer and hold the call through the application server / resume or hang up. Here, the first terminal is an ordinary terminal, including: a public switched telephone network telephone or a wireless mobile terminal; the second terminal is an intelligent terminal, including: a hardware terminal based on the SIP protocol or a client software or a web page of a PC .

[0040] Specifically as shown in accompanying drawin...

Abstract

This invention relates to a call control method, a system and devices, in which, the method includes: a calling user calls a unified number, a first terminal corresponding to the unified number responds it and turns on the speech channel with the calling user, an applied server transmits an event notice of responding the talk of the first terminal to a second terminal corresponding to the first one and the second one transmits a call control request to the applied server, which controls the talk between the calling user and the first terminal. This invention also includes a system for controlling calls including: an applied server, a first terminal and a second terminal. This invention also includes an applied server and an intelligent terminal.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a call control method, system and equipment. Background technique [0002] The unified communication service is a comprehensive intelligent service. It takes the unified number as the core and shields the communication differences between the user's SIP (Session Initiation Protocol) intelligent terminal, traditional PSTN (Public Switched Telephone Network) telephone, mobile phone and other terminals. Through the integration of various communication methods, it provides users with more complete communication solutions and business experience. [0003] In the prior art, on the basis of unified communication and unified number, the user can answer the call through the SIP intelligent terminal, and complete control operations such as call hold, recovery, and transfer of the terminal's voice channel; the user can also use the unified number to hide the call. However, d...
