You will need to also figure out the rest of it.  You cant say a server will support x phones.  Different phones have different "weights" as do Gateways, H323, Media Resources, MOH, etc.

Run through the sizing tool:


It will walk you through how many devices your server will support based upon MCS server and devices.

But roughly, any 7845 model can support up to 7500 phones.
