Abstract
Call management techniques are implemented using a call routing engine. In the invention the routing engine centrally controls a public network to facilitate implementation of post-routing call processing of a call. The call routing engine provides switching which makes the public network appear as under the control of a virtual switch. Control of the public network by the call routing engine appearing as a virtual switch may implement post-routing call processing of telephone calls.
