Re: [OSL | CCIE_Voice] Single Cluster redundancy
SRST is your best bet. It is not possible to merge both East and West site into a single cluster b/c Cisco requires max. round trip delay between two CUCM servers with in a cluster to be less than 40ms.

Re: [OSL | CCIE_Voice] Single Cluster redundancy
in order for you to do that all the servers must be members of the same cluster. so on the callmanager group you can point your phones to the server that you want. . the phones can have up to 3 redundant servers. other than that SRST is your only potion 2010/5/19 Mav > Hello, > > > I know that each cluster can have only one PUB ,my question is : in the > scenario tha ACME company has two single Cluster one in NY and the other in > LA ,both have one PUB and one SUB, the two site have 10 MB Point to Point, > in the event that LA servers burn down, would it be possible have LA fail > over to NY and have the phone register with the NY cluster ? or SRST is the > only solution? > > > Thanks. > ___ > For more information regarding industry leading CCIE Lab training, please > visit www.ipexpert.com > > ___ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
[OSL | CCIE_Voice] Single Cluster redundancy
Hello, I know that each cluster can have only one PUB ,my question is : in the scenario tha ACME company has two single Cluster one in NY and the other in LA ,both have one PUB and one SUB, the two site have 10 MB Point to Point, in the event that LA servers burn down, would it be possible have LA fail over to NY and have the phone register with the NY cluster ? or SRST is the only solution?
