About LAI
With Look-Ahead Interflow (LAI), you can optionally route a call to a backup location based on
your system’s ability to handle the call within parameters defined in a vector. In turn, the backup
system can accept or deny the call also based on parameters defined in a vector.
LAI requires end-to-end ISDN connections, and it works over private and public networks.

ISDN routing with LAI enabled: All calls routed over ISDN facilities by a route-to number with
cov n or route-to digits with cov n vector command on a communication server where
Look-Ahead Interflow is enabled are treated as Look-Ahead Interflow call attempts.

Look-Ahead Interflow
A vector may route a call over an ISDN facility to a destination that is not a VDN. The sending
communication server processes this call as a Look-Ahead Interflow call even though it is not.
ISDN processing at the receiving communication server causes the call to always be accepted.
However, the DNIS and any other information in the Look-Ahead Interflow information
forwarded with the call are ignored.

Also you may be thinking about Best Service Routing???
