The Call Park application allows an Enterprise Voice user to put a call on hold from one telephone and then retrieve the call later from any telephone. When the user parks a call, Microsoft Communications Server 2010 transfers the call to a temporary number, called an orbit, where the call is held until someone retrieves it or it times out.

You need to configure the Call Park orbit table with the ranges of extension numbers that are reserved by your organization for parked calls. These extensions need to be virtual extensions: extensions that have no user or phone assigned to them. Each Communications Server 2010 pool where a Call Park application is deployed and configured can have one or more orbit ranges. Orbit ranges must be globally unique across the Communications Server 2010 deployment.
