extension, or a particular agent. An adjunct can also provide priority ringing and
priority queuing.
Sending the Call Route Request
Here’s an example of a simple vector that uses adjunct routing:
Figure 9-1. Adjunct Routing Vector
In this vector,
1111
is the extension number of an ASAI link. Each ASAI link has a
unique extension number, even in a configuration where there might be multiple
ASAI links to the same adjunct.
When a call encounters an
adjunct routing
command, and if the call is not
queued to a split, the switch sends an ASAI message requesting a call route over
the specified adjunct link. The following list identifies the contents of the
message, along with a comment or a brief explanation for each item:
■ Calling number information. Calling party number or billing number
(CPN/BN) provided by ISDN-PRI facilities, or by the administered
destination for other trunk facilities. If the call originates from a local switch
extension, this extension is the number dialed (after digit translation).
■ Called number. Originally called extension (if a call is forwarded to a
VDN), or the first VDN through which the call was routed (if the call was not
forwarded to the VDN).
■ Routing VDN. Last VDN that routed the call to the vector that contains the
adjunct routing
command.
■ Call identifier. ASAI identifier that permits the ASAI adjunct to track
multiple calls via either Event Notification or Third Party Call Control. (See

, 555-
230-204, or the

,
555-230-220, for more information on ASAI.)
■ Look-Ahead Interflow information (if any). Includes the original VDN
display information and the priority level of the call at the originating
switch. (See Chapter 8.)
■ Digits collected via Call Prompting (if any; maximum of 16 digits). Digits
are collected by the most recent
collect digits
command. (See Chapter
5.)
