Restoring a a CUCM with cluster over the WAN

            Does anyone has recommended bandwidth, delay  for doing a CUCM recover in a CUCM clustered over the WAN?

Subscriber are remote and PUB is in a datacenter.

Thx

There is no specific requirements for restoring servers. If you are inquiring about requirements for deploying CUCM cluster across WAN those are very well documented in SRND from bandwidth and latency perspective. Assuming you have CUCM 7+ you need at least 80 ms latency and 1.5Mbps for each remote sub for DB replication + 1.5mbps (total) for ICCS traffic, so if you have 2 remote subs you would need 3mbps  + 1.5mbps.

HTH,

Hi Chris

Yes, I know the requirements for clustering over the WAN. I was looking if there was any requirements for doing a recovery on a Cluster that have subscribers over the WAN.

No special requirements, perform restore as documented. To save time it would be helpful to have the DRS backup locally with Pub.
