CER with Multiply CUCMs

Tommer Catlin · ‎05-11-2009

I cant find anything in the documents, but does CER support multiple clusters, or is one to one CER to one cluster?

Hey Tommer

this is most possible:

Creating Route Patterns for Inter-Cisco Emergency Responder Group

Communications

Before You Begin

The dial plans must be unique between all Cisco Unified CallManager

clusters supported by a Cisco ER cluster. For example, in the network

shown in Figure 3-1, the extension 3003 can only be defined in Cisco

Unified CallManager cluster CCM-B.

They should all run the same CUCM version, CER must support the number of users you will have and CUCM/CER should not be separated by a WAN.
