Phoning on several lines (multi-line)
Line keys
Line keys can be set up on the freely programmable feature keys on a
OpenScape Desk Phone CP200. Any key assigned the “Line” function corres-
ponds to a line, and so up to 4 lines can be set up.
A distinction is made here between primary and secondary lines. Each of these
line types can be used on a private or shared basis page 91.
Line keys are set up by the administrator responsible.
The following graphical example displays how phones are connected within a
team with several line keys.
3234 is the extension number of Mr. Meier, 3235 that of Mr. Müller, and 3236 that
of Mr. Schulze. All three lines can be used to phone from all three phones. The
line of the phone’s own secondary extension number if, however, always the pri-
mary line.
Primary line
All multi-line telephones have a primary line. This line can be reached in the
usual manner via your public phone number. Incoming calls to your number are
signaled on this line.
Secondary line
A secondary line on your phone is used as a primary line by another participant.
At the same time, your primary line can be set up as a secondary line for another
phone in the system.
To avoid conflict between individual multi-line phones, "Do not disturb"
and "Call forwarding" can only be used for the primary line.
