is is possible to have 2 callmanager clusters share 1 gateway? gateway is a a vg200 configured on first ccm cluster as an h323 gateway. It has two pri's terminated on it each with separate blocks of DID's. We need to add another callmanger cluster to the mix to support a new customer and I was wondering if I could continue using the same gateway. My voip dial-peers on the gateway now are someting like
dial-peer voice 100 voip
incoming called-number .
progress_ind setup enable 3
voice-class codec 1
voice-class h323 1
session target ipv4:172.16.0.4
ip precedence 5
I was thinking I migh could do something with the destination-pattern part of the dial-peer config to route calls to a certain block of DID's to another callmanager cluster.
The two pri's are not needed for company A, just got two for redundancy. Plan is to use the vg200 and two pri's for trunking to PSTN until we need more then upgrade to a as5350 or some other device to terminate the PRI's.
This is for an ip centrex offering and the second callmanager cluster is for a big customer that wants more control over their own phone system but doesnt want to have to deal with the local rboc for trunking.
