encountering an originating trigger including a feature code and querying a service control point (SCP) to obtain instructions for routing the communication, wherein the SCP determines whether a calling line associated with the first calling line number is subscribed to VAD service;

if the calling line is subscribed to VAD service, establishing a call path between the calling line and an intelligent peripheral with voice recognition and processing capabilities, wherein the intelligent peripheral prompts collection of an utterance from the calling line, translates the utterance into identifying information associated with a called line and extracts a transaction identification (ID) from a called party parameter, wherein the transaction ID comprises a first plurality of digits in the first calling line number associated with the calling line used to establish the call path with the intelligent peripheral and wherein the intelligent peripheral is identified by a second plurality of digits in the first calling line number associated with the calling line used to establish the call path with the intelligent peripheral;

receiving a message that includes the identifying information at the SCP; and

dropping the call path between the calling line and the intelligent peripheral when the SCP receives the first calling line number and transaction ID from the intelligent peripheral, wherein the transaction ID is created and maintained on the SCP from the time the query is made to the SCP to obtain instructions for routing the communication until the call path between the calling line and the intelligent peripheral is dropped, and completing the communication between the calling line and the called line, wherein the SCP instructs a service switching point to route the communication to a called party.
