Complete a screen for each LAI vector.

  • If Lookahead Interflow (LAI) is administered as n on the receiving communication server, interflow still results on a look-ahead basis. However, the forwarded DNIS, sending communication server VDN name, and information is ignored and tandem LAI is not provided.

  • Administer the Outgoing Display field to n to not update the call originator display on each LAI call attempt.

  • Administer the Interflow-qpos EWT Threshold field when working with enhanced LAI. Any calls answered before this threshold do not interflow, saving CPU resources on the communication server.

  • Administer a CPN prefix for each VDN that maps to a vector used to place LAI calls. If you do not administer the CPN Prefix field, the phone displays an LAI DNIS with all blanks.

For private network non-QSIG connectivity with direct facilities between the communication servers, administer LAI DS1/E1 circuit packs with Country Protocol Option 1 independent of the country where the system is located.
