[cisco-voip] Expressway MRA question

[James Buchanan]

Hello,

It is indeed possible. You use one cluster as a sort of "hub" cluster.
Then, just make sure the users in each cluster have the Home Cluster
parameter checked, but make sure it is only checked in one cluster. Also,
you have to make sure you are using ILS and have peer links in IM&P between
all the clusters. If all the Jabber users can talk to each other today in
all the various clusters, then you're already grand for using Expressway in
that scenario.

Thanks,

James
