VoIP Telephone Configuration Guide
Page 8 of 88
Handset phone
Used to denote a telephone from the GAI-Tronics Titan or Commander product ranges, with a
separate handset attached to the main telephone body by a heavy duty flexible cord. No
separate loudspeaker is fitted to these models.
Hands-Free phone
Used to denote a telephone from the GAI-Tronics Help Point or Vandal Resistant product
ranges, with a microphone and speaker integrated into a flat panel. No corded handset is
fitted to these models.
LNR
Standing for “last number redial”, this is a button provided on some models of GAI-Tronics
phone to redial the last manually dialled number.
Memory dial number
On an analogue or cellular phone, memory numbers are pre-stored digit sequences used to
start calls. With VoIP these can also be URI’s rather than numbers, but are still referred to in
the same way.
Mute
A function to temporarily mute the microphone so that the remote party cannot hear. On GAI-
Tronics telephones this function is provided by the "S" button.
NU tone
Number unobtainable tone – used to indicate that a call cannot connect due to the end point
not being recognised.
Off hook
Used to denote the state of a telephone during an active call, or when a call has been
initiated. For a handset phone, off hook usually means that the handset is lifted.
On hook
Used to denote a telephone in the idle state – no call started or answered. A telephone is still
on hook when it is ringing on an incoming call. For a handset phone, on hook usually means
the handset is not lifted. If a call is terminated whilst the handset is still lifted (for example by
the CALL LIMIT timer), the telephone is placed into the on hook state. For a hands-free
phone, on hook means that no ON or WAKE & DIAL button has been pressed following a
terminated call or reset.
Recall
On analogue phones, the Recall button is used to activate exchange signal, usually to
transfer a call. The GAI-Tronics VoIP telephone does not have a recall facility, but the “R”
button (where fitted) can be used to activate an output on a remote phone, for example as a
door release.
Register Fail tone
A tone played to the user initiating a call to indicate that the telephone is not currently
registered with a registrar, meaning that a call cannot be made.
Ring tone
A tone played to the user initiating a call to indicate that the call has been placed but not yet
answered. This usually signifies that the remote end is ringing.
Ringing
A loud alert tone made by the telephone indicating that an incoming call is ready to be
answered.
Secrecy (mute)
A function to temporarily mute the microphone so that the remote party cannot hear. On GAI-
Tronics telephones this function is provided by the "S" button.
