Making calls in the team 71
MultiLine
The following is a description of the telephony scenarios for multi-line phones.
Refer to page 78 for a detailed description of the settings.
Line/trunk keys
Line or DSS keys can be configured by your administrator on programmable
keys on the OpenScape Desk Phone CP200/CP205. These line keys cannot be
changed or deleted by the user.
Each key programmed with the "Line" function corresponds to a line. This
means up to 3 lines can be configured on the function keys. A distinction is made
here between primary, secondary and phantom lines. Each of these line types
can be used on a private or shared basis
page 71.
Primary line
All multi-line telephones have a primary line. This line can be reached in the usu-
al manner via your public phone number. Incoming calls to your number are sig-
naled on this line.
Secondary line
A secondary line on your phone is used as a primary line by another subscriber
of the line trunk group. Your primary line, which is configured on another tele-
phone of a line trunk group, simultaneously functions as the secondary line on
that telephone.
Phantom line
Phantom lines are not used as primary lines by any telephones in a line trunk
group. Phantom lines are established, for example, when the number of lines
provided by a communications system exceeds the number of available tele-
phones.
Line utilization
• Private line: A line that is used by a single telephone. This line cannot be used
as a secondary line by another telephone.
• Shared line: A line that is configured on multiple telephones. The line status
is displayed for all telephones that share this line. If, for example, a shared line
is being used by a telephone, a status message indicating that this line is busy
is displayed on all other telephones.
• Direct call line: A line with a direct connection to another telephone.
The status of a line can be established in the team menu from the icons.
This function is not available to you on an OpenScape 4000, see
page 162.
To avoid conflict between individual multi-line phones, the functions "Do
not disturb" and "Call forwarding" can only be used for the primary line.
