Look-Ahead Interflow
8-12 Issue 4 September 1995
■ 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.
