Deply AAR between two clusters

Dear All,

I have two site A et B with a cluster of two callmanagers in every one. Hereafter more details:

Saite A:

=======

- Range of internal DN: 1XXX

- Range of External number: 88XX

- router pattern : 2XXX to trunk

Saite B:

=======

- Range of internal DN: 2XXX

- Range of External number: 98XX

- router pattern : 1XXX to trunk

these sites are connected by a link (512K)where 33% is reserved for voice trafic. a trunk was setup for inter cluster communications to ensure 10 calls simultanously, but I want that if there more calls (>10), to re-route via PSTN to second site.

Please any idea to implet AAR service.

Thanks in advance,

Re: Deply AAR between two clusters

AAR would not really work here. You should use Route Groups and Route Lists here. Add the ICT and PSTN Gateway to individual Route Group and then both of them to one Route List. Have the ICT as the first option for this. Here you can even do digit manupulation based on the Route Group the call would be sent through. Once this is done, set the Location Badwidth for the Router Gateway to 240 (10 G729 calls) and once the Location has no Bandwidth, the call would automatically be sent using the PSTN Gateway.

Please refer the following links for information about how to configure:
