I need to configure AAR in one of the UC labs. I have a question here regarding the Dial prefix. There are two dial prefixes.One from this group another to this group.
I am not sure whats the use of Prefix(to this group).For example I have two sites one Central and one remote.They are kept in different location ie.,Location1(cnetral) and Location2(remote) and in two AAR groups AAR1 and AAR2. When the bandwith between these two locations set to zero,the call should be routed to PSTN. So the prefixes are attached from the originating AAR Group and sent to the Respective GW.
In this case whats the use of Prefix(to this group)?. Isnt Prefix from this group is sufficient?.
Any clarification on this highly appreciated.
