Hands-Free Answer on Intercom (HFAI)
Hands-Free Answer on Intercom (HFAI)
Description
This feature allows the following voice terminals to provide hands-free answer service on
eligible incoming calls; each terminal must have Automatic Answer (AUTO ANS) assigned to
a flexible button.
● BIS (7305H03B, 7305H04C, 7313H01A, 7314H01A, 7316H01A, and 7317H01A) and
HFAI (7309H01A); these sets provide full service without requiring adjuncts.
● 10-Button (7303H01B), 34-Button (7305H01B), and 34-Button Deluxe (7305H02B)
equipped
with a Hands-Free Unit (HFU—a S102A Speakerphone); these
arrangements provide full HFAI service.
● 5-Button (7302H01C) and the 10- and 34-Button sets listed above, not equipped with
an HFU; these arrangements allow callers to
“voice announce” their calls, but the
terminal user must use the handset to reply.
Calls Eligible for Hands-Free Service:
● Inside calls (that is, calls from one System 25 set to another System 25 set using a
System Access, Loop, DSS, or Auto Intercom button).
● Calls transferred from another System 25 set using the Transfer feature. The
transferring station may pass both inside and outside calls in this way. Note that
calls transferred by the attendant are indistinguishable from calls transferred by any
other station.
Calls Not Eligible for Hands-Free Service:
● Incoming trunk calls (Personal Line, DID, DGC).
● Calls extended by an attendant.
BIS and HFAI Voice Terminals
LEDs next to the AUTO ANS button and the HFAI/Mic (HFAI set) or HFAI (BIS set) button
indicate whether the HFAI feature is enabled. The LEDs are turned on and off by pressing
the adjacent buttons.
When both the AUTO ANS and HFAI LEDs are on, the set will auto-
answer eligible calls.
The HFAI LED will wink (on HFAI sets) or light steadily (BIS sets) during HFAI calls.
The set's response to HFAI-eligible calls depends on the status of the HFAI and AUTO ANS
buttons and LEDs, as follows:
● If both HFAI and AUTO-ANS LEDs are on:
