Calling a System Telephone Extension
A System telephone is a Dukane-supplied ATEL or STEL; or an “off-the-shelf” DTMF
telephone or CTEL. If your System has been networked to other Systems using a NIC,
you can call any telephone in the networked Systems. If your System has not been net-
worked, you can only call the telephones in your own System.
Note:
An extension can only be called if its telephone ring access class of service attribute
is enabled. If this attribute is disabled and the telephone is associated with a speaker,
the caller will be directly connected to the speaker. If the telephone is not associated
with a speaker then the caller will hear the reorder tone in the handset.
1.
ATEL: Lift the handset for a private conversation or press SPKR PHONE for
speaker/microphone conversation.
STEL, DTMF telephone, or CTEL: Lift the handset.
2.
ATEL: Dial the extension number.
STEL, DTMF telephone, or CTEL: Same as ATEL.
3.
ATEL: After hearing the called party answer, speak normally into the handset or
toward the microphone.
STEL, DTMF telephone, or CTEL: After hearing the called party answer, speak
normally into the handset.
4.
ATEL ONLY: If you are using the speaker phone function, stop speaking to listen
for a reply from the other extension.
5.
ATEL ONLY: Pressing the MUTE function (F6 factory default) will alternately mute
and unmute both the transmitter and receiver in handset operation, or mute and
unmute the panel microphone in speaker/microphone operation.
6.
ATEL ONLY: If push-to-talk speaker/microphone operation is desired, press and
release TALK to manually control the audio direction. The MUTE function is not
available in this mode of operation.
7.
ATEL ONLY: If you are using the speaker/microphone, you can adjust the speaker
listen volume by pressing the VOL up/down key.
8.
ATEL: Hang up the handset or press SPKR PHONE to end the call. Failure to
replace the handset in the cradle will cause the ATEL to switch to an on-hook mode
of operation after a preset duration. If the ATEL converts to an on-hook mode, it still
rings as if the handset is in the cradle, therefore no calls are missed.
STEL, DTMF telephone, or CTEL: Hang up the handset to end the call.
Note:
The handset must be on-hook for a minimum of two seconds to end the call.
