Possible outcome
If a digital station attempts to transfer the two parties together, the call-
appearance lamp flutters, indicating a denial. If transferring over a DCS
trunk, the denial may drop the call since the transfer is allowed, and the
other system is queried for disconnect supervision.
If an analog station attempts to transfer two parties together by going
on-hook, the analog station is no longer on the call and the transfer
cannot be denied.
If a CAS attempts to transfer two parties together by pressing the
release key, the release link trunk is released and the branch attempts a
transfer by hanging up.
If a station conferences every party, the conference is allowed since the
station has disconnect supervision. When the station is dropped from
the call, the call is dropped since the other parties do not have
disconnect supervision.
If a station is call forwarded off-premise to a trunk without disconnect
supervision, the calling party without disconnect supervision is routed
to the attendant.
