Making calls with multiple lines
When configured (ask relevant Administrator), you can belong to a team of
members with multiple lines: team or executive/secretary groups.
Line/trunk keys (MULAP keys)
page 162 are available on your phone.
Trunks
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
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 participant.
Your primary line, which is configured on another telephone, simultaneously
functions as the secondary line on that telephone.
Private line
A line that is used by a single telephone. This line cannot be used as a second-
ary 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 sharing the line.
Direct call line
A line with a direct connection to another telephone.
You can see the status of the line from the LED.
Line Seizure
The line assignment is dependent on the configuration (ask your responsible Ad-
ministrator). If the automatic line seizure is configured, a line is automatically as-
signed upon lifting the handset or pressing the loudspeaker key.
