Embodiment Construction

[0041] In order to make the objectives and technical solutions of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0042] The present invention is a VOIP-based call control method. When the PSTN telephone terminal as the calling party initiates a call to the IP telephone terminal as the called party, after the called party goes off-hook, the FXO port is off-hook.

[0043] figure 2 An exemplary flowchart of a call control method according to the inventive concept is shown. see figure 2 , this method keeps the state of the FXO port consistent with the state of the bound FXS port, and executes call control according to the following steps:

[0044] In step 201, the calling party's PSTN telephone terminal calls the called party's IP telephone terminal. When the FXO port corresponding to the calling party is in an idle state, the PBX sends a message to the FXS port bound t...

Abstract

The invention discloses a call control method based on VOIP, which keeps the state of the FXO port of the external exchange office consistent with the state of the bound FXS port of the external exchange station. The method includes: A. Calling party public switched telephone network PSTN telephone The terminal calls the called party's Internet protocol IP telephone terminal. When the FXO port corresponding to the calling party's PSTN telephone terminal is in an idle state, the private branch exchange PBX calls the FXS port bound to the FXO port through the FXO port; B. When the caller's IP telephone terminal goes off-hook, the FXS port and the FXO port are converted to off-hook state. The invention also discloses a voice gateway, which includes: bound FXO ports and FXS ports. The invention can avoid false billing when the PSTN telephone terminal is the calling party and the IP telephone terminal is the called party, and improves the accuracy of billing.

Description

technical field [0001] The present invention relates to Voice Internet Protocol (VOIP) technology, in particular to a VOIP-based call control method and a voice gateway. Background technique [0002] With the rapid development and wide application of network technology, VOIP services that utilize network resources to implement voice communication are becoming more and more common. In order to realize the intercommunication between IP telephones and commonly used public switched telephone network (PSTN) telephones, FXS voice gateways with external switching station (FXS) ports are used to connect ordinary telephone terminals, so that ordinary telephone terminals can be used as IP telephone terminals to access the In the IP network; the FXO voice gateway with the external exchange office (FXO) port is used to connect the PSTN telephone terminal, and bridge the PSTN and IP network. Through the FXS voice gateway and the FXO voice gateway, the intercommunication between IP telep...
