Supporting Multiple Line Keys Per Line
Each line on the phone can be configured to have more than one Line Key
associated with it. This enhances call visualization and simplifies call
handling. If this is the case, the display could resemble the following figure:
Incoming calls to this line will be distributed evenly among the available Line
Keys. Similarly, outgoing calls will be distributed.
Your phone can be configured to have a combination of lines with a single Line
Key and lines with multiple Line Keys.
Supporting Shared Lines
Your SoundPoint IP 650 supports shared lines.
A shared line is indicated by a different line icon. In the following figure, the
lines 3161 and 3163 are private and the line 3166 is shared.
If two phones share a line, an incoming call to that number will cause both
phones to ring. The call can be answered on either phone but not both.
Calls on shared lines can be transferred, put on hold, or added to a conference.
Note
Shared lines are an optional feature and may not be supported on your particular
system. For more information, contact your system administrator.
