Multiple Represented Directory Number
Your extension number can be programmed on a dedicated key on other
system telephones, i.e. your number is “represented” on these phones.
Other extension numbers can of course also be “represented” on your
phone.
Note: This feature has to be programmed by your system
administrator.
Incoming calls
Incoming calls can be answered (indicated with a flashing key lamp,
calling party information and/or ring signal) on all phones where the
number is represented.
Outgoing calls
The dedicated key can be used to call the programmed extension. How
outgoing calls are handled depends on the programming of the phone,
please contact your system administrator regarding this.
