Routing telephone calls

摘要

An incoming telephone call is received at a private branch exchange. The telephone call is directed to a telephone extension of the private branch exchange. A call routing preference associated with the extension is determined and the telephone call is routed based on the call routing preference. If the call routing preference is set to a first preference, telephone call is routed to a telephone associated with the extension. If the call routing preference is set to a second preference, the telephone call is routed to a computing device associated with the extension.
