CamelCase 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. See also AIN, DISA, KTS, PBX, and PSTN. |
