Calls Generally
Calls are dropped.
Deskset cannot make or receive phone calls
On external calls, you hear an excessive echo at the Deskset.
Probable Cause Corrective Action
Restoring Deskset settings or
updating software while that
extension is in use will cause
all calls to be dropped.
 Your system administrator should avoid updating
software or restoring Deskset settings when you
are likely to be using the phone.
The network is down.
 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.
The Deskset extension was
changed during the call.
 Contact your system administrator. If changes
were made to your extension while you were on
a call, that call is dropped.
Maximum Call Duration was
exceeded.
 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.
Probable Cause Corrective Action
Your Deskset is not
synchronized.
 Press (MENU) –> 4 to verify that the
Deskset Status is Synchronized. See “Deskset
cannot make or receive phone calls and the
Deskset screen displays Synchronizing....” on
page 112.
Your Deskset is not
connected to the LAN.
 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.
Probable Cause Corrective Action
The automatic Gateway line
calibration did not run
properly.
 See your system administrator. There may be
non-system equipment connected in parallel to
the telephone line.
