Problems solved by technology

However, this is mainly to ensure the reliability of the equipment. If the IP network is interrupted, the IP phones in the remote site will still become unavailable due to the loss of contact with the headquarters network.
In addition, when both the active and standby voice servers fail, the IP phones at the remote site will also be unavailable, although the probability of this happening is very small

Embodiment Construction

[0050] In order to solve the problems existing in the prior art, the present invention proposes a method for realizing IP phone escape, that is, by pre-designating the escape device in the remote site by the voice server in the headquarters network, when the voice server is unavailable, the escape device can Complete the call to the IP phone in the remote site according to the IP address in the call routing table.

[0051] Before introducing the specific implementation plan, the escape device is described as follows: the escape device is a standard Linux device running the escape module, which can be a separate computer, server or embedded device, or integrated into the voice gateway. The escape module is a software based on the Session Initiation Protocol User Agent (SIP UA), which can complete software download, registration to the voice server, subscription, receiving notification, and call routing. In this embodiment, a separate computer, server or embedded device is used ...

Abstract

The invention discloses a method for realizing internet protocol (IP) telephone escape, which is applied in a voice Over Internet Protocol network. The method comprises the following steps that: a voice server in a headquarter network preassign an IP telephone charged by escape equipment in an remote station; and when the voice server is unavailable, the escape equipment finishes calling of the IP telephone in the remote station according to escape information calls route list generated from the voice server. The invention also discloses a communication device for realizing the IP telephone escape. Through the method and the communication device, the IP telephone in the remote station can also dial and answer a call when the voice server is unavailable, and the IP address of the IP telephone can be changed.

Description

technical field [0001] The invention relates to the technical field of Voice over Internet Protocol (VoIP), in particular to a method and a communication device for realizing the escape of an Internet Protocol (IP) phone. Background technique [0002] With the rapid popularization of IP networks, VoIP, as a new application, has developed rapidly and has become the mainstream choice for enterprise internal communication networks. In the VoIP network, the IP phone is the most important terminal device, and it is an important carrier for users to use various services. Therefore, once the IP phone is unavailable, the user cannot communicate. [0003] There are many reasons for the unavailability of IP phones, such as: voice server failure, IP network interruption, IP phone failure, power outage, etc. In the design of the VoIP network, various means will be used to improve reliability, such as: active and standby server redundancy, IP network redundancy, and POE power supply fo...
