I have a CCM running on 7825-MCS server, and I'm in a middle of migration process, so I want to reuse this same 7825-MCS server as a backup (failover) for my current 7825-MCS unity server
it's a 7825-I3 server
what's else other than the failover license i need to purchase
my second question is how many voicemail users can these both MCS-7825 servers in this case support?
is it 1000 users only?
can i have a solution using these two 7825 servers to support more than 1000 users
