Inter-cluster communication over PSTN when locations at maximum bandwidth

[Nis24601]

AAR does not work between clusters. 

So for example, if we had set between a location and a trunk a maximum number of calls to 3, and then wanted the fourth call to go through PSTN similarly to AAR, how would we do it? 

Obviously we would need a route pattern that would add the external number mask. But how would we prevent that call from being dropped in the first place? 

Many thanks

AAR will consider the bandwidth under the Phone and Trunk Location.


If you are using only g711 calls, since only the payload is considered for the location, you will need 3x64kbps = 192kbps


You may check the following links to understand how much bandwidth if required for each codec.
