Embodiment Construction

[0025] like figure 1 As shown, communication terminals A and B belong to a voice dedicated line group, and communication terminals C and D belong to a voice dedicated line group. Communication terminals A and C are respectively connected to communication terminals B and D through an IP network. A set of IP voice dedicated line control equipment can support multiple voice dedicated line groups. The IP voice dedicated line control device 1 on one side of the IP network is configured with two voice dedicated line groups private-line AB and private-line CD, and the IP voice dedicated line control device 2 on the other side of the IP network is configured with two voice dedicated line groups private-line BA and private-line DC.

[0026] like figure 2 As shown, the IP voice dedicated line control device includes a call control module, a dedicated line group management module, and a conflict detection and avoidance module.

[0027] Taking the AB dedicated line group as an exampl...

Abstract

The invention provides an IP (Internet Protocol) voice private line control method and IP voice private line control equipment for realizing the same. The IP voice private line control equipment of a calling party detects the off-hook of the calling party and then acquires the number of a called party by finding a voice private line group of the calling party; and the IP voice private line control equipment of the called party receives a call, then detects the states of the called party and carries out different operations according to detected different states of the called part. The invention can achieve the effect that the called party rings as long as the calling part is in the off-hook state without dialing because one IP voice private line control equipment can support a plurality of voice private line groups; and no matter the called party is in any state, no matter the called party is in the off-hook state (in the traditional call control method, if the called party is in the off-hook state, the called party returns a busy tone to the calling party, and the call can not be communicated), or the calling party and the called party are simultaneously in the off-hook state, communication can still be ensured.

Description

technical field [0001] The invention relates to a call control technology in the field of VoIP (Voice over Internet Protocol). Background technique [0002] In actual voice communication application scenarios, there is a demand for dedicated voice lines. For example, between emergency dispatching systems, network management centers, and other occasions that involve confidentiality or require high connection reliability. [0003] For a non-IP network environment, a physical leased line can be deployed to achieve this purpose, and signaling such as PRI can be run on it. In this way, the physical isolation of the line from the outside world can be guaranteed, and the reliability of call connection can be guaranteed extremely high. [0004] Although the physical leased line method is very good, it is not practical for many users when the distance is long. Today, with the increasingly developed IP network, there are more and more application requirements for establishing IP vo...
