For LT-S ports, only basic call functions are provided - you cannot use other functions
(transfer, forward, hold etc) from an LT-S terminal. However, a DGP can transfer/forward a
call to an LT-S terminal. Other features (conference, hold etc) operate in a similar way.
There is no COS check for an LT-S port.
