HANDS-FREE ANSWER ON INTERCOM (HFAI)
Description
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 and 7305H04C) 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 102A 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:
The following types of calls are eligible for HFAI 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).
● V1 Only: Incoming calls extended by the attendant are eligible for HFAI service at
BIS sets but
not at HFAI sets. However, HFAI sets may be translated as BIS sets
and will then provide HFAI service on attendant extended calls (see “Interactions,”
below, for more information).
For V2, no outside (trunk) calls extended by the attendant are eligible for HFAI
service.
●
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.
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:
—
The set generates a tone burst over its speaker to indicate an incoming call
(the calling party also hears this tone).
—
The parties may converse.
The called party can speak in a normal voice
toward the set. No other action by the
called party is required.
