Call Mangers Clusters

[Pabloduarte]

We are looking to Cluster Call Managers in a Wan Enviroment.

I am looking for some information on doing this succesfully but everthing that I find on CCO is for Lan Clustering and Call Manager 3.0. we arevcurrently running Call Manger 3.1.1 and would like to Upgrade to 3.1.4b before Clustering the Call Mangers. I would be interested in any comment suggestions or if someone has a whitepaper on Clustering Call Manger 3.1 please send me the Link.

Thanks for all the Help

Hi,

http://www.cisco.com/warp/customer/779/largeent/netpro/avvid/IPtel_srnd.pdf

It's a new ip telephony design guide for CallManager 3.1-3.2 .Clustering are discussed in chapters 2 and 6 .Basically a cluster is limited to 10,000 phones and if you like to have a cluster over WAN you must have at least 10 Mb link. Take a look at device weights as well ( Chapter 6 page 3) .

Hope it helps,

Marina
