Shared Lines
The telephone supports shared lines
**
.
A shared line is indicated by a different 
line icon. In the diagram, the first line is 
private and the second line is shared. If two 
telephones share a line, an incoming call 
to that number will cause both telephones 
to ring. The call can be answered on either 
telephone but not both. 
If a shared line is in use on one of the tele-
phones, it cannot be used on the other one. 
The shared line icon changes to a moving 
icon and the line LED turns red when the 
line is in use remotely. 
Calls on shared lines can be transferred, put 
on hold, or added to a conference.
Voicemail and Voice and Text Messaging
Users can send and receive both Voice
*
and
Text messages on the telephone. Received 
messages will be indicated by a flashing 
Message Waiting Indicator LED on the 
front of the telephone and optionally a 
visual notification on the display. 
Individual line indicators reflect voice or 
text messages left on that line (useful if 
multiple lines are in use).
A stutter dial tone in place of normal dial 
tone is used to indicate that one or more 
voice messages are waiting at the message 
center.
SIP Instant (Text) Messaging is supported 
in real-time. Users can send and receive 
text messages using their telephones.
