Abstract

The invention discloses a network telephone switchboard for expanding special calls and an implementation method thereof. The network telephone switchboard comprises a user authentication module, a cluster call module, a strong call module, a group call module and a voice cache module, the user authentication module is respectively connected with the cluster call module, the strong call module and the group call module, the cluster call module and the group call module are connected with the voice cache module, the user authentication module is used for initiating authentication of a calling user initiating a special call; the cluster call module, the strong call module and the group call module are separately used for providing three functions of cluster call, strong call and user group call of one-master-multiple-salve; and the voice cache module is used for caching, superposing and mixing network voice data streams flowing by the switchboard. The network telephone switchboard disclosed by the invention can perform audio calls with standard SIP telephones on the market depending on an SIP protocol stack, can make ordinary phones real audio and video on demand call, strong call and cluster call functions, and has an ad hoc networking function.

Description

technical field [0001] The invention relates to the fields of voice communication, network exchange and audio-video conference, in particular to an Internet telephone exchange for extending special calls and a realization method thereof. Background technique [0002] Traditional telephone exchanges are generally divided into two types: one is a program-controlled voice exchange, which converts the analog voice transmitted by the second-line telephone into a digital signal, and exchanges the digital signals of different input lines through a time slot exchange chip or FPGA. The function of voice exchange; the other is a network telephone switch deployed on a network server that supports the sip protocol. Customized equipment for the protocol—convert the input voice into network data, communicate through the signaling of the sip protocol, and realize the exchange of network data to achieve the purpose of voice exchange. [0003] The concurrency of traditional program-controll...
