Abstract: In today's network, enhancing or otherwise modifying signals in bearer flows in or at equipment already deployed in a network may be done by modifying or upgrading existing equipment, or otherwise invasively routing signals through identified network elements. In accordance with example embodiments of the present invention, signals for control plane flows are transparently monitored using policy based routing to direct control signals from a routing point to a signaling monitoring point. Bearer plane address information of a selected media processing point is substituted for other bearer plane address information in the control signal in a manner that causes subsequent bearer flows to be directed to the selected media processing point from the routing point by destination based routing. Bearer flows may be directed to a media processing point to apply signal enhancement to an encoded media signal on the bearer flows to produce an enhanced media encoded signal.
