Look-Ahead Interflow (Category A only)
Interim call handling before LAI is accepted by receiving
communication server
Until the look-ahead attempt is accepted by the receiving communication server, the caller
continues to hear any feedback applied by the sending communication server vector and
will remain in any split/skill queues.
Call handling with Route-to number or Route-to digits handling with coverage y
Route-to number with coverage y or route-to digits with coverage y commands never result
in a Look-Ahead Interflow call attempt. The sending end assumes the call is always going
to be accepted. This command always completes the call. Moreover, the command should
not be used if the vector at the receiving communication server might deny the call, since
the caller in this case would be given a busy signal or would be disconnected. Use this
command with coverage y only when you want unconditional interflow (with Look-Ahead
Interflow active) and the terminating communication server is set up accordingly.
Continuity during call transfer between communication servers
Audible feedback may be provided to the caller before interflow is attempted. Therefore,
another audible feedback from the receiving communication server may confuse the caller.
For example, a caller hearing ringback on the sending communication server may be
confused if music is applied suddenly when the call interflows to the receiving
communication server.
Backward compatibility of LAI applications
For backward compatibility of LAI applications between Avayacommunication servers,
leave the "Send Codeset 6/7 LAI IE" option on the Trunk Group form set to its default y.
Existing LAI applications will continue to operate as before, even after you upgrade.
You can use enhanced LAI available in the communication server without any network or
trunk administration changes, by adding the interflow-qpos conditional to original LAI
vectors (the conditional applies only to calls in queue). Interactions
AAR/ARS
ISDN facilities used to provide Look-Ahead Interflow to a VDN on another communication
server in a private network can use the AAR feature if private facilities are to be used for
call routing.
Agent Telephone Display
If collected digits are forwarded with an interflowed call, the forwarded digits are displayed
to the answering agent (unless they're overridden with newly collected digits) on the
telephone display.
