How many phone are required?

With Cisco you have an option to deploy Cisco Callmanager Express (up to 240 phones) which resides on a router, or server based Cisco CallManager (a cluster can support up to 30,000 phones). There are some feature differences between the 2.

You can get more details in the data sheets:
