Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings. In the present invention, the call server is not restricted to use any hardware platform, and logically can be H.323 gatekeeper, soft switch, SIP server, VOIP gateway, etc. in the VOIP network.

[0024] The specific H.323 network architecture is taken as an example for illustration. Such as image 3 As shown, the gatekeeper acts as a call server, phone A is a user of gateway 1, phone B is a user of gateway 2, and phone C and fixed phone D are users of gateway 3. Gateway 1, gateway 2, and gateway 3 are all registered on the gatekeeper, first configure the number priority list on the gatekeeper, that is, configure the number and its corresponding priority. These numbers can be telephone numbers within the IP telephone network, or fixed telephone numbers outside the IP telephone network, mobile phone numbers, PHS numbers, etc. The phone number that needs to be demolished...

Abstract

This invention provides one method based on number priority calling and to the sound system based on internet and one control method between the interface gate and servo. This invention matches phone number priority through servo with strong dissemble function interface network gate through getting number priority and the network gate judges the calls number priority to achieve sound system interfacing method. This invention is of IP telephone system number to provide one priority to realize network all phone number and IP calls to support priority plug to ensure the emergency call normal on VOIP network.

Description

technical field [0001] The invention relates to an Internet-based voice system, in particular to a control method between a voice access gateway and a server. Background technique [0002] In some existing government departments, such as courts, public security, military, etc., in order to ensure the smoothness of some emergency calls due to safety and emergency considerations, there must be some mechanism to realize the forced demolition function, that is, when the called number When the line is busy, the emergency calling number can disconnect the current call of the called number and preempt the conversation with the called number. [0003] In the current VOIP (Voice over Internet) network composed of gateways and gatekeepers, as attached figure 1 , for the VOIP gateway GW1, the three phones A, B, and C are called internal phones, and D, E, and F are called external phones; on the one hand, GW1 can communicate with PSTN ( The telephone D conversation that is connected...
