Description (partial)

Calls are getting leaked for CFNA scenarios, so the busy trigger gets triggered even when there are no active calls which leads to incoming call failure for that Line.

A ---------------> B(CFNA) ------- > Voice Mail

Phone A calls phone B and Phone B rings and never answers the call and due to CFNA setting call gets routed to Voice mail.
Before the call routs to voice mail phone A hangs up the call.
