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 ?
