Troubleshooting
Corrective Action
Your system administrator should avoid updating

software or restoring Deskset settings when you
are likely to be using the phone.
Ensure that the Ethernet cable is securely

plugged into the Deskset network port (labeled
) and that the other end is plugged into
your office LAN.
Contact your system administrator. If changes

were made to your extension while you were on
a call, that call is dropped.
None. Outside calls that are forwarded or

transferred to an outside phone number use two
outside lines for the duration of the call. To avoid
tying up two lines, the duration of such calls is
limited by a timer that your system administrator
sets.
Corrective Action
Press (MENU) –> 4 to verify that the

Deskset Status is Synchronized. See
cannot make or receive phone calls and the
Deskset screen displays Synchronizing...." on
page 112.
Ensure that the Ethernet cable is securely

plugged into the Deskset network port (labeled
) and that the other end is plugged into
your office LAN.
Corrective Action
See your system administrator. There may be

non-system equipment connected in parallel to
the telephone line.
