•
Facility Busy Indication
You can administer a busy-indicator button for a wideband-endpoint extension, but the button
does not accurately track endpoint status.
•
Facility Test Calls
You can use Facility Test Calls to perform loop-back testing of the wideband call facility.
•
Generalized Route Selection
GRS supports wideband BCC to identify wideband calls. GRS searches a route pattern for a
preference that has wideband BCC. Route preferences that support wideband BCC also can
support other BCCs to allow different call types to share the same trunk group.
•
CO Trunk (TTC - Japan) Circuit Pack
This circuit pack cannot perform wideband switching. No member of the circuit pack should be a
member of a wideband group.
CallVisor Adjunct-Switch Application 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 may 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
).
For a simple ASAI configuration example, see
