The precedence of this call details entry in the event of call collision. Call collision occurs when an
incoming call for a given details entry is detected while an outgoing call is waiting to complete. This
object configures whether the router treats the incoming or outgoing call as having precedence. Since the
device at the other end will also probably be experiencing a call collision, the precedence should be
configured to the opposite value at the other end. Setting this object is current on row creation.
