RTT within a callmanager cluster ?

Hiya,

Using a CCM Cluster, I understand that servers need to talk to each other under a specific RTT (I think 50ms).

Or is this only for inter-cluster trunks ?

Any views would be helpful

Thanks

Re: RTT within a callmanager cluster ?

You need no more than 40ms RTT between any two cluster members in order for your installation to be TAC-supported. This makes it difficult to set up East coast/West Coast clusters in the US but does permit most shorter distances. The bandwidth specification is a little more complicated, and I suggest you read the CallManager 3.3 SRND here, which is the source of that information:
