[cisco-voip] Expressway MRA question

[Ahmed Abd EL-Rahman]

Hi James,

Yes currently all the 4 clusters' users can talk to each others via inter-cluster trunks over WAN links.

Kindly if you have any documents explaining such setup please share it with me.

Appreciated.

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

Hi Gents,

If we have 4 standalone clusters each of them has its own CUCM and IM&P servers (version 11.5), I’d like to know if it’s possible to have only 1 Expressway C and E system to serve all the 4 cluster with MRA service ?

Taking into consideration that all the 4 clusters are using the same DNS system and same domain name (company.com<http://company.com>).
