AT&T 555-230-520 manual Originator’s Display, Dnis Information Displayed for LAI Scenarios

Look-Ahead Interflow

■Call routes to a VDN

■DNIS name field is not blank

The type of DNIS information that is displayed depends upon a number of different scenarios. This information is presented in the following table:

NOTE:

VDNs that map to vectors that place Look-Ahead Interflow calls must have their ISDN Calling Party Number (CPN) prefixes administered. If an ISDN CPN prefix is not administered, the assigned VDN name is not sent, instead a DNIS of all blank space characters is sent and displayed on the answering agent’s terminal.

Originator’s Display

For internal calls, the originator’s display contains the same information as for Basic Call Vectoring. However, it is possible the originator might receive undesirable display updates during Look-Ahead Interflow call attempts. To avoid this scenario, ensure that the Look-Ahead Interflow calls are going out over trunk groups with the “Outgoing Display” field set to no. When the display field is set to no, internal callers calling that trunk group will see the digits that they dialed on their display.
