[cisco-voip] Split CM Cluster

[Andrew Dignan]

The old SRND guide said that 900k was needed "per" callmanager in a
cluster to split it.  The new SRND guide says 900k per 10,000 BHCA (I
think this is slightly higher, if you use Cacti to monitor the bandwidth
its about 1200k from what I have seen).  Anyway, is this to say that if
you have 5 CallManagers in a cluster.  3 in one site and 2 in another site
but less than 10,000 BHCA you only need about a T1?  That just doesn't
seem right to me.
