VCMs are your call resources. When a phone goes off-hook, a VCM is used. VCM is also used for any TDM to IP conversion, such as when an IP endpoint is interfacing with a PRI. VCMs and PRIs are separate resources but used together.

250 sounds like adequate resources for a 25 phone page but if you find usage is high during peak hours, consider using shuffling (I think IPO calls this direct media) to enable two IP endpoints to exchange RTP directly to free up VCMs after call setup.
