DNIS information displayed to answering agent

Last Updated : Sep 08, 2012 |

For LAI, the DNIS name, which is the called VDN name from the sending switch, is presented on the display for the answering agent on the receiving switch if all of the following are true:

  • The LAI option is enabled.

  • The call routes to a VDN.

  • The 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.

Scenario

Tandem LAI call

Look-Ahead Interflow DNIS information from the original LAI call.

If multiple VDNs are accessed, the name of the VDN that was last accessed by a route-to command.

Sending switch sends a blank DNIS Name field (that is, a name is not assigned to the sending switch called VDN) or the trunk group is administered to not send the LAI name.

Name associated with the receiving VDN. This name can be changed according to the rules of VDN Override at the receiving switch.
Note:

VDNs that map to vectors that place LAI 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.
