The R1.5 Signaling is a special state machine for Russia to support R1.5 signaling. The IDLE
signaling is asymmetrical which means that the state machines have to distinguish the
direction of a call. Therefore there are different modes for incoming and outgoing calls that
can be used for a call in one direction. The two new types are supported in FXS Mode only
