When you use that command as the last step, Communication Manager removes the call from the queue before call processing continues to subsequent vectors through a route-to VDN command.
When Communication Manager routes the call to the another VDN, Communication Manager:
Ends vector processing of the previous vector.
Removes the call from any split queue or skill queue that the previous vector processing step establishes for the call.
Continues call processing in the vector assigned to the routed-to VDN.
