  Initiate T.38 switchover when acting as called party, regardless of FAX direction.
  
  SendFAX() and ReceiveFAX() can be given options to indicate whether they should
  act as the calling or called party; this mode should be used to decide whether
  to initiate a switchover to T.38, not the direction that the FAX transfer will
  take place.
