Problems solved by technology

In this case, it will not only cause false billing between off-hook and on-hook at the FXO port, but also cause the calling party user to hear the ringback tone first and then hear the busy tone, which is not in line with the user's usage habits

Embodiment Construction

[0041] In order to make the purpose and technical solution 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 call control method based on VOIP, and its basic idea is: when the FXS port is in the off-hook state due to the IP phone terminal talking with other IP phone terminals, the FXO port corresponding to the FXS port is off-hook, and when 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 picks up the hook, the FXO port is picked up.

[0043] figure 2 An exemplary flowchart of a call control method according to the concept of the present invention is shown. see figure 2 , this method keeps the state of the FXO port consistent with the state of the bound FXS port, then follow the steps below to perform call control:

[0044] In step 201, th...

Abstract

A method for controlling call based on voice Internet protocol includes calling FXS port bound with FXO port by special packet switch PBX through FXO port when FXO port corresponding to PSTN telephone terminal of calling party is on idle state if Internet protocol IP telephone terminal of called party is called by PSTN telephone terminal of calling party, switching FXS port and FXO port on off-hook state when IP telephone terminal of called party is off-hooked. The voice gateway for realizing said method is also disclosed.

Description

technical field [0001] The 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 use network resources to realize voice communication are becoming more and more common. In order to realize the intercommunication between the IP phone and the commonly used public switched telephone network (PSTN) phone, the FXS voice gateway with the external exchange station (FXS) port is used to connect the ordinary phone terminal, so that the ordinary phone terminal can be used as an IP phone terminal to connect to the In the IP network: use the FXO voice gateway with the external exchange office (FXO) port 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 the IP telephone termina...
