The Line Restrictions feature lets the administrator restrict the calls permitted to and from a given station. Originating line restrictions refers to restrictions on calls placed from a station; terminating line restrictions refers to restrictions on calls being terminated at a station.
The administrator can assign this feature to the entire BG (Business Group) or to individual subscribers.
Because line restriction is not a visible subscriber service, it does not increment a visible usage counter.
Lotus Sametime Unified Telephony checks line restrictions before completing calls and performing call transfers. If a call is found to be in violation of configured restriction levels, the system routes the call to error treatment and subsequently releases it.
The line restrictions feature is known as station restriction, too.

Calls originated at a semi-restricted line and directed to a line outside of its business group and/or calls directed to a semi-restricted line from a line outside of its business group are routed to error treatment (usually reorder tone or special intercept announcement).
A fully-restricted line has all of the attributes of an semi-restricted line. In addition calls directed to a fully-restricted line from the business group attendant, as well as calls originated at a fully-restricted line and directed to the business group attendant, are routed to error treatment (reorder tone or special intercept announcement).
Fully-Restricted Lines with Attendant Access
A fully-restricted line with attendant access can access the attendant for information and to requests transfers to another DN within the business group. Lotus Sametime Unified Telephony does not permit the attendant to transfer a DN with this restriction to points outside of the business group, as well as attempts by the attendant to transfer calls from outside the business group to a DN with this restriction.
