Gatekeeper Routing
|

| Andrew Dignan 2005-05-25, 5:45 pm |
| 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

| 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.
