      This issue happens when a fax call is sent from one FS v1.6.14 to another FS v1.6.14.

      1) FS1 sends INVITE to FS2
      2) FS2 sends 200 OK with Session-Expires: 120;refresher=uac
      3) FS2 sends T38 reinvite
      4) FS1 sends 200 OK
      5) 60 sec later FS1 sends a new T38 reinvite
      6) FS2 sends 488 Not acceptable here followed by a BYE message
