6. When there is no route that supports Q-SIG, IS-11572 protocol in the route selection data from a calling
party to a called station, Call Forwarding service is activated without rerouting function.
In this example, since the Q-SIG, IS-11572 line cannot be selected for a route from Station A (calling
station) to Station C (forwarded station), rerouting function is not activated even if RT1 or RT2 is idle.
