Configures answer supervision for the appropriate voice port. Answer supervision (when the far end
answers the call) is indicated by using reverse battery polarity. This is valid for an outbound call
only. On an FXS interface type we respond to LSAS (Line Side Answer Supervision) signaling on
the T1. Our response is to reverse battery polarity on (T-R). Telco must configure their T1 for LSAS
if this is not a point-to-point T1.
