Usage
Enter y to queue calls for the announcement if the Type field is
integrated, integ-rep or aux-trunk. The caller is always connected to the
beginning of the announcement. Enter y for ACD and vectoring delay
announcements. Call centers should always use this option.
No queue and no barge-in. The caller is always connected to the
beginning of the announcement. The announcement does not play if a
port is not available.
Enter b to set up barge-in if the Type field is integrated, integ-rep or
aux-trunk. When Type is integ-mus, this field defaults to b. Callers are
connected to the announcement at any time while it is playing.
Note: The same non-barge-in announcement can be played through
more than one port (or all ports) of an integrated circuit pack. The initial
request to play an announcement selects an available port on the board
on which the announcement resides. If there are additional requests to
play the announcement while it is playing on another port(s), another port
is selected. If all ports are busy, new requests to play announcements go
to the integrated announcement system queue (Q field must be y).
Otherwise, the request to play is denied, and processing continues
without the caller hearing the announcement. When a port becomes
available, all queued calls (up to the platform "calls connected" limit) are
connected at the same time to hear the announcement play from the
beginning.
A barge-in announcement starts playing when first requested and
continues playing through a port, repeating until there are no more
requests. Call processing simultaneously connects calls to the playing
barge-in announcement. Each call remains connected until the
requesting feature operation removes the call (for example, wait step
times out). Barge-in type announcements never select another port to
play the same announcement once it is playing on a specific port.
