clustering over the wan

i am trying to deploy cm,cuc,imp with deployment model clustering over the wan but i have read SRND and see Bandwidth requirements for clustering over the wan is too much for unity and impresence

i will deploy both servers which contains pub and sub in a lan and move the server that contains subs to the remote site

does i need 5 Mbps for impresence redundancy group only and about 7Mbps for for cuc 50 port

takecare that my installation is with 2 BE6000 M servers

my question is what is the required Bandwidth for clustering over the wan CUCM ,CUC and IMpresence ?

How long is a piece of string

How long is a piece of string?

The way I always designed it is accordance with Cisco's 6 Class QoS model, which contains a 5% of bandwidth guarantee for call signalling. It always served me well, but i wouldnt present this as a one size fits all, but more as a starting point.

i want to know the bandwidth

i want to know the bandwidth required in Mbps between site 1 contains pub for each application  and site 2 contains sub for each application 

We replicate, CUCM and CUPS,

We replicate, CUCM and CUPS, CUC across the WAN and it roughly sits between 0.5 and 1 Mbps  combined
