Conference call
This allows three callers to carry out a conversation together.
DTMF
Dual Tone Multi Frequency - a method of sending signals over
a telephone link. Each digit dialled represents a combination
of tones.
Enquiry call
During a call you may call a second person. As soon as you
dial the second number, the first call is automatically put on
hold. When you have finished your enquiry call you may
return to your initial call.
Feature codes
Most of the programmable features may be activated by
dialling a specific number (see page 1).
“Follow me” forwarding
When you are away from your own extension, “follow me”
forwarding allows you to receive your calls at your current
extension. This feature is activated at the destination
extension.
Forwarding
Redirecting calls to another destination.
Hold
You may place a call on hold in order to carry out another
function or to prevent the caller from hearing you.
Hunting group
A group of extensions which are linked by a code number.
When this number is dialled the system ‘hunts’ for a free
extension within the group. Any extension within a group may
answer a group call by entering a feature code.
Intrusion
If an extension or line is busy you may be authorised to
intrude on that extension, in order to contact the person
urgently.
