1.3 System Features
Extension Group
Description
To support efficient utilisation of extensions, they can be grouped together as an Extension
Group. Any extension in the Extension Group can pick up a call ringing at another extension
within the same Extension Group (Call Pickup - Group).
Extension Group is used to direct incoming calls (both extension and outside) to a group of
answering extensions associated with the type of incoming calls.
Up to 128 Extension Groups can be created in the system.
The following seven different types of Extension Group can be created:
Group Type
Terminate
Circular
Ring
Operator
VM(Voice Mail) All the VM ports are searched until an idle one is found to permit VM Service.
AA (Automated
Attendant)
UCD (Uniform
Call
Distribution)
Conditions
• Log-in, Log-out
Members of an Extension Group (except Group Type:None) can leave the group
temporarily when they are away from their desks, to prevent calls being sent to their
extension (Log-out). They can return to the group when they are ready to answer a call
(Log-in).
• A single extension user cannot belong to two or more different Extension Groups at a time.

If the called extension is busy, Station Hunting redirects the incoming call to an idle
extension within the same Extension Group. The extensions are searched until
reaching the extension which has the highest physical port number in the group
(Station Hunting Group - Terminate).
If the called extension is busy, Station Hunting redirects the incoming call to an idle
extension within the same Extension Group. The extensions are searched in
physical number order (from lower to higher) of the extension port until an idle one
is found (Station Hunting Group - Circular).
All the extension in the Ring Group ring simultaneously.
Within an Operator Group, an operator-seeking call (extension / outside) may come
in on a single operator (Single) or all operators in the group simultaneously (Multi)
depending on System Programming.
All the AA ports are searched until an idle one is found to permit AA Service.
Successive calls go to a different extension each time a call is received. Extensions
are hunted in a circular way.
