dial external numbers with just one button press. Configure speed dials under User
Preferences, User speed dials, Speed dial #XX. (Services, Telephony Services, System

Phantom DNs
A Phantom DN is a DN record for a telephone that does not physically exist. You can
assign lines to the telephone that can be programmed to Appear and Ring. This allows you
to assign an Answer key from the non-existent telephone to an existing telephone. This
might be used in the case where a customer number has been changed, but the number still
gets used. Rather than assign a telephone to the line, you can create a phantom DN and
assign an Answer key to an active telephone.
pickup group
You can place a telephone into one of nine call pickup groups. You can pick up a call
ringing at a telephone within a pickup group from any telephone within the same pickup
group. Assign a telephone to a pickup group under Capabilities. (Services, Telephony
Services, System DNs)
