Dial Plan - Outbound calls to 2 gateways

[Serey]

Hi all,

I have configured one analog-PSTN-Voip Gateway and one VoIP provider. I would like that :

- By default all outbound calls go trough the analog-PSTN Gateway
- If the PSTN line is busy, a second outbound call goes trough the VoIP gateway.

Is it possible to change the dial plan behavior when the IP PBX detects a busy line ?

Thanks,

Fabrice

To answer this question you have to understand what a dial plan does, it is build up out of possible 5 :

Endpoint addressing
Path selection
Calling privileges
Digit manipulation
Call coverage

These components are addressed when the caller dials the digits.

What you want is call fail over, i am not aware that 3cx deals with this. It uses the gateway it is told to use based upon the dailout rule.

I see a feature request comming up here and that is:
use the next available gateway when dialing out (or incomming) should be configurable.

Back to your question.

The closes you can get to that now is to have a dial out rule per gateway, so that when the caller gets an engage signal they can use the other gateway by using a different prefix.

At this point in time I do not believe that this is done by 3cx, the SPA3102 has a fail over feature that can be used but that is on ata level and outside the control of 3cx.
