call pick-up - Computer Definition
A voice telephone system feature that enables users in a programmed call pick-up group (e.g., workgroup) to answer calls for each other. In a key telephone system (KTS) environment, a user can pick up a call at any phone where the line appears by dialing a feature code, usually of three characters. In a PBX environment, an authorized user can enter a code on the set keypad or by depressing a designated feature button on an electronic set, with no line appearance on the set necessary. Call pick-up service, also known as call notification service, is defined in the advanced intelligent network (AIN) specifications as a service of the public switched telephone network (PSTN) that provides for calls to be answered automatically by a voice processor. The called party can be notified of a deposited voice message by pager, fax, e-mail, or other means. The caller can enter a privilege code provided by the called party to distinguish the priority of the calling party. To pick up the call, the called party dials a direct inward system access (DISA) port on the network switch and enters password codes in a manner similar to that used to access contemporary voice mail systems.
