Abstract
The present invention discloses a method for selecting voice routes, which comprises the following steps: a priority is set for each voice route; the initial value of the actual priority of each voice route is equal to the value of a configuration priority; a voice gateway receives calling and then selects the current voice route with the highest actual priority to call continuously; if continuous calling is unsuccessful, the actual priority of the voice route having the continuous calling failed is reduced. The present invention simultaneously discloses a voice gateway, which comprises a voice route priority saving and setting module and a voice route selection module. After the voice route with the high priority is interrupted, the present invention receiving successive calling does not select the voice route preferably; thus, the present invention enhances the successful speed of the continuous calling, and shortens the time of calling establishment; further, the actual priority of the voice route of which the actual priority is lower than the configuration priority is reset the configuration priority after the preset time so that the present invention can use the interrupted voice route restored in time.
Description
Technical Field
The invention relates to the technical field of voice calling, in particular to a method for selecting voice routing and a voice gateway.
Background
With the wide application of voice over ip (voip) technology, dialing schemes are more and more abundant, and the requirements for rationality and operability of number management are increasingly obvious while service flexibility is improved and the requirements of multiple users are met. For the same call, when there are multiple voice routes to reach the called party, the voice gateway needs to decide the sequence of selecting the multiple voice routes.
In practical networking there are usually two routes for a call to reach the called party, one through the IP network and the other through the Public Switched Telephone Network (PSTN), and the IP network route is usually selected first. When the voice gateway receives the call, the IP network route is preferentially selected to realize long-distance bypass, if the IP network can not continue the call, the call is not released, and then the PSTN route is selected to continue the call. The purpose of improving the call completing rate can be achieved through the voice route backup.
When there are a plurality of voice routes at the same time that can match the same call number, the voice route to be used should be selected according to a predetermined rule. The common rule is priority, that is, the priority of each voice route is configured on the voice gateway, the voice route is selected for the call according to the priority of the voice route, and when the call of the voice route with high priority fails, the voice route with the next priority is selected for the call. The disadvantages of this method are: when the voice route with high priority is interrupted due to network fault and other reasons, the voice gateway still selects the voice route with high priority every time the voice gateway receives a call, and when the call fails, the voice route with low priority is selected for calling, which obviously increases the call setup time greatly.
Disclosure of Invention
In view of the above, the present invention provides a method for selecting a voice route and a voice gateway, so as to reduce the call setup time.

C. the voice gateway reduces the actual priority of the voice route which causes the call connection failure, and then the step B is carried out.
The step A further comprises the following steps: presetting the number of stages for reducing the actual priority of all voice routes each time;
step C, the voice gateway reduces the actual priority of the voice route which causes the call connection failure to be as follows: and according to the preset reduction grade, reducing the actual priority of the voice route with the call connection failure.
The preset number of stages for reducing the actual priority of all voice routes each time is as follows: the number of steps of lowering the actual priority of all voice routes each time is set to be the same.
The preset number of stages for reducing the actual priority of all voice routes each time is as follows: and setting the number of stages of each voice route, in which the actual priority of each voice route is reduced, to be different according to different configuration priorities of the voice routes.
Step C, the voice gateway will reduce the actual priority of the voice route with the call connection failure, and at the same time, further includes: and starting a timer, and resetting the actual priority of the voice route to be the same as the configured priority when the time length of the timer is longer than the preset time length.
