Problems solved by technology

First of all, when all the telephones connected to the FXS interface can be connected to the call control equipment, they use the telephone number inside the VoIP system. The number is not uniform under the conditions, which brings difficulties to the use
Secondly, when the call control equipment fails, FXS is bound to FXO, and the internal telephones connected to FXS cannot communicate with each other

Embodiment Construction

[0031] First, the VoIP analog gateway device for implementing the internal switching method of the present invention will be described below. see figure 1 As shown, the VoIP analog gateway includes: at least one FXO interface, at least two FXS interfaces, at least one IP network interface, a system control module, an IP network detection module, an internal switching logic module, a packet conversion module, an automatic voice response device and an data storage device. Among them, the FXO interface is connected to the existing public telephone network (PSTN) through the telephone line, and the FXS interface is also connected to a separate telephone set through the telephone line. There is no fixed ratio between the number of FXO ports and the number of FXS ports. The IP network interface connects the call control equipment through the IP network.

[0032] see figure 2 As shown, inside the VoIP analog gateway, the IP network detection module is connected to the IP network...

Abstract

The invention discloses a VoIP analog gateway for achieving conversation under fault condition and an internal exchange method. The VoIP analog gateway may be switched between a logon operation state and an internal exchange operation state. In the logon operation state, the VoIP analog gateway periodically logs on call control equipment, and enters the internal exchange operation state if the logon operation fails. In the internal exchange operation state, the analog gateway processes a call request according to information pre-configured in a data storage device in the logon operation state, and respectively processes the requests according to conditions. By using the invention, the VoIP analog gateway can locally communicate with each other to achieve call communication when the call control equipment fails, when the IP network fails, or when the VoIP gateway fails to connect the call control equipment.

Description

technical field [0001] The present invention relates to a VoIP analog gateway and an internal switching method for realizing calls under fault conditions, and in particular to a method for realizing intercommunication within the gateway and between the gateway and the public telephone network in the event of a fault in the network or call control equipment The internal switching method and the VoIP analog gateway implementing the method belong to the technical field of Internet voice communication. Background technique [0002] VoIP is a technology that converts voice or fax signals into data packets (Data Packet), and uses Internet Protocol and corresponding call signaling to transmit voice over IP network. Its implementation process is roughly divided into the following steps: first, it encodes the analog voice information at the calling end; then it compresses the voice data packet, and adds address and control information at the same time; then, transmits the encapsulate...
