the originating user.

The CALL TRANSFER - ALL CALLS [C-11] feature operates as follows:
a.) If the restricted station is the controller, the station cannot add a trunk from which this station is
restricted.
b.) If the restricted station line is not the controller, the controller cannot connect the restricted
station line to a trunk from which the station is normally restricted.

Two outgoing trunk group restriction tables are provided per system. The Direct Dial Access table is
indexed when a user dials the trunk group access code, and the ATTENDANT CONSOLE [A-3] table is
indexed on Attendant completed calls. The restriction options per RSC can differ per table, thus allowing
Attendant completion of outgoing calls for restricted stations.
