call when it comes into a station, manipulate the call while it is at the station, and 
invoke station features like lighting the message waiting light, setting Send All 
Calls, or Call Forward.
These capabilities could be used, for example, to provide an integrated voice 
and electronic mail system for office personnel. With this system, office personnel 
can have a message waiting light turned on whenever an electronic mail 
message is received or get an electronic mail message when a voice mail 
message arrives. Another application is a “Follow-me” call forwarding 
application, in which calls are automatically forwarded to different locations 
based on a schedule entered by the user.
The CallVisor ASAI capabilities and features can be used to support a variety of 
applications in the call center environment — as well as office automation 
applications that include directory services, message desks, and phone 
management. CallVisor ASAI-based applications let DEFINITY ECS and your 
computers share and use information, complementing and enhancing the 
communications and data-processing capabilities these systems deliver. These 
capabilities can help you streamline operations, improve productivity, and 
improve customer satisfaction.
Architecture
ASAI integrates the DEFINITY ECS with main-frames, minicomputers, personal 
computers (PCs), and distributed computing environments (such as LANs and 
client-server environments) for call center and office automation applications. In 
an inbound call center, agents use a telephone and a computer connected to a 
computing environment. The computer uses information it receives over the ASAI 
link to display information about incoming calls on the agent’s terminal.
In outbound call centers, the agents’ equipment is similar, but the computing 
environment uses the ASAI link to make outbound calls. ASAI also shifts agents 
from inbound to outbound service and back. It can be used to provide 
screen-based dialing and other office automation applications.
An ISDN primary rate interface (PRI) link provides calling-party and called-party 
information to the various applications. This link is not required, but it lets 
applications use network information provided by ISDN to broaden its scope. 
Without a PRI link, automated voice response units can still gather information 
needed by prompting with DNIS.
Application Programming Interface
ASAI provides an applications programming interface, which can be used by 
vendors to develop computer-telephone integration applications. The applica-
tions programming interface supplies the syntax and operation of the function 
calls used to invoke ASAI capabilities. The interface can be used to communi-
cate with vendor-specific application interfaces. For example, IBM has an appli-
