Adjunct Routing

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:

1.adjunct routing link 1111

2.wait-time 60 seconds hearing ringback

3.route-to number 0 with cov n if unconditionally

4.disconnect after announcement 2000

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 DEFINITY Communications System Generic 3 Feature Description, 555- 230-204, or the DEFINITY Generic 3 CallVisor ASAI Technical Reference, 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.)
