Abstract
The invention relates to methods and apparatus for determining whether a CPS should employ a standard interface or an unreliable network for routing telephone calls. The invention includes a telephone call switching apparatus which includes a routing engine configured to receive a telephone call from a terminal connected to the call switching apparatus and a switching matrix connected thereto. The telephone call includes a destination code. The routing engine is configured to receive the telephone call from a terminal or trunk line, determine an unreliable network route for the telephone call based upon the destination code, and provide a message to a call manager associated with the unreliable network route (via the switching matrix). The message includes the destination code. The routing engine is also configured to receive a response from the call manager; and route the call over the unreliable route if the response is affirmative.
