Managing Data Calls

CallVisor Adjunct-Switch Applications Interface

CallVisor Adjunct-Switch Applications Interface (ASAI) links Avaya Communication Manager
and adjunct applications. The interface allows adjunct applications to access switching features
and supply routing information to Communication Manager. CallVisor ASAI improves Automatic
Call Distribution (ACD) agents' call handling efficiency by allowing an adjunct to monitor, initiate,
control, and terminate calls on the media server. The CallVisor ASAI interface can be used for
Inbound Call Management (ICM), Outbound Call Management (OCM), and office automation/
messaging applications.
CallVisor ASAI is supported by two transport types. These are:
1. Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) transport (CallVisor
ASAI-BRI)
2. LAN Gateway Transmission Control Protocol/Internet Protocol transport (Avaya LAN
Gateway).
CallVisor ASAI messages and procedures are based on the ITU-T Q.932 international standard
for supplementary services. The Q.932 Facility Information Element (FIE) carries the CallVisor
ASAI requests and responses across the interface. An application program can access
CallVisor ASAI services by supporting the ASAI protocol or by using a third-party vendor
application programming interface (API).
