Problems solved by technology

[0004] It can be seen from the above process that the IP voice gateway must have voice interface card hardware, and must support PSTN voice protocol signaling and IP voice protocol signaling and the function of mutual conversion between the two, which greatly increases the software of VoIP networking. hardware cost

Embodiment Construction

[0044] The core idea of ​​the present invention is to establish an IP channel between the main and called traditional gateways directly connected to the main and called PBXs for transmitting voice signaling and data. Specifically, a transmission control protocol (TCP) channel is established in the IP channel for transmitting voice signaling; at the same time, one or more user datagram protocol (UDP) channels are established in the IP channel for transmitting voice data .

[0045] In the present invention, a traditional gateway refers to a gateway that only has an interface for transparently transmitting voice signaling or data supporting the PSTN voice protocol, but does not have any processing function for voice signaling or data.

[0046]The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Abstract

The disclosed system and method for VoIP business builds an IP path with a TCP path and a UDP path between traditional gateways connected to the calling and called PBXs; sending the voice signaling or data from calling PSTN to the called gateway and then to the called PSTN user. This invention needs no voice interface hardware or IP voice gateway to reduce cost for VoIP network greatly.

Description

technical field [0001] The invention relates to the technical field of voice communication, in particular to a system and method for realizing Internet protocol voice services. Background technique [0002] The application of Voice over Internet Protocol (VoIP) on routers enables voice services such as traditional telephone services to be carried on IP networks. VoIP is implemented through voice packets and is mainly a software solution, but it needs to install a modular voice card on the router to support voice transmission in the IP network. [0003] The telephone service implemented on the Internet is called Internet telephony, and Internet telephony is an early form of VoIP service. figure 1 Network structure diagram for implementing VoIP services, such as figure 1 As shown, the IP voice gateway in the figure provides two interfaces at the same time: one is an interface that supports the public switched telephone network (PSTN) voice protocol, such as: E1 or T1 interfa...
