[cisco-voip] Gatekeeper Routing

[Walenta, Phil]

If they are sending the PSTN call to a PRI, you shouldn't need the 1 as
the setup message should notify the PSTN that it's a national call.

Subject: [cisco-voip] Gatekeeper Routing

I have 3 CallManager clusters and I am using a gatekeeper to route calls
between the clusters.  This environment has a 10 digit dial plan so what
I am doing is anytime someone dials 91[2-9]XX[2-9]XXX I strip of the 91
and send it out a Route List that first sends the call to the gatekeeper
and
secondly to the PSTN (that Route Group prefixes "1").   The call will
fail
to the PSTN route group if the gatekeeper is either down or not enough
bandwidth is avaialable between zones.  This is working fine.

What I am trying to find out is if the gatekeeper doesn't not have a
"zone prefix" that matches an incoming request can I have it fail and
have CallManager interpret that to prefix the 1 and fail to the PSTN
route group (just as it does if there isn't enough bandwidth available).
Or, do I have to create tons of Route Patterns that match each clusters
DID ranges and ONLY send those calls to gatekeeper.  If so that kind of
defeats the purpose of a gatekeeper for easier dial plan management.

Thanks,

Andy Dignan
