Computer Telephony Integration Capability

Description
Computer Telephony Integration (CTI) coordinates communications between computers and the
telephone system. This is accomplished by using a Telephony Application Programming Interface
(TAPI) server to connect the DBS 576 with a Local Area Network.
LAN TAPI is designed to enhance the DBS 576's performance by supporting both standard and
custom computer telephony applications. A TAPI Service Provider (TSP) resides on a host computer
running Windows NT Server/Version 4.0 or greater. Beginning with Version 3.0 and higher, CTAPI
has been added to support LAN TAPI. (See LAN TAPI on p. 3-36 for additional information.)
