Managing Data Calls
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).
For a simple ASAI configuration example, see
