Problems solved by technology

[0012] For the current gateway device with relatively high port density, the application environment of the device may be an enterprise, so the internal calls of the enterprise may be more frequent, and the calls between the gateway device and the company's external phone may be relatively less. The existing technical solution There is no distinction between local switching and IP switching services, so for frequent local calls, it cannot reduce delay or effectively improve call quality
In addition, if the local switching voice data packets also need to be processed by the CPU, as the port density of the device increases, the processing capacity of the CPU must also increase a lot, which may increase the cost of the CPU and thus increase the cost of the device

Abstract

The disclosed VoIP gateway comprises: based on prior art, adding a time-slot exchange chip and DSP, and using a microprocessor to distinguish local and IP dialogue. This invention reduces time delay and cost, and improves voice quality.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a VoIP (VoiceOver Internet Protocol, Internet-based voice transmission) gateway and a method thereof for realizing a time slot switching function. Background technique [0002] VoIP refers to a technology for transmitting voice data packets through an IP network. At present, with the improvement of VoIP-related signaling control protocols, the quality of voice signal codecs is getting higher and higher, and the network bandwidth is getting wider and wider. The quality of the voice signal transmitted through the IP network has been getting higher and higher, and has basically reached the level accepted by users. VoIP signaling control technology is becoming more and more mature, and various VoIP network equipments have also been launched by various network equipment suppliers. The application of VoIP technology is more and more extensive. [0003] A VoIP gateway refers to a...
