Base: Each telephone comes with a base that allows
you to adjust the telephone to either of two positions
for the comfort of the user. The base can also be used
to easily mount the telephone on the wall.
Communication: Models of the Avanti family of
telephone sets are available with full duplex and half
duplex communication. Full duplex enables both parties
to speak and be heard simultaneously. The Avanti 3025
at the top of the range is full duplex. The Avanti 3015H
and Avanti 3000, the sets without displays, are half
duplex. The other sets are available in full-duplex or
half-duplex models.
Operation: Basic telephone operation is consistent
throughout the line of Avanti telephones. However,
each telephone can be programmed to support specific
features and to operate in either Key or PBX mode.
Hot dialpad: Dial without lifting the handset or
pressing a speaker/intercom button. The station
speaker is automatically activated when any button
on the dialpad is pressed, for internal dialing, when
pressing an outside line button to initiate external
dialing, or for operating system features.
Distinctive station ringing: By selecting any one
of the available distinctive ring tones for a station,
users can easily recognize when their station rings.
Handsfree Answerback (HFAB): Answer a voice
call received through the station speaker handsfree,
via the station microphone, without having to lift
the handset or press the SPEAKER button.
