Used on a per-trunk basis to define if a Trunk line is to be either a Metering Pulse
Detection(MPD) or a Polarity Reversal Signal(PRS) trunk.
An MPD Trunk will detect a C.O-provided meter pulse. A Polarity Reversal trunk will
detect the line reversal signal which may be provided by the Trunk Line when the other
party answers the outgoing call or the outside party clears the call.

duration timer is stopped and call is released.
