Symptom
My Deskset does not receive
incoming calls.
On outside calls, I hear an
excessive echo at the
Deskset.
My Deskset is not active
immediately after a power
interruption.
Troubleshooting
Synapse Administrator's Guide
Probable Cause
Incoming call notifications
have been suppressed or are
unable to reach the Deskset.
The automatic PSTN
Gateway line calibration did
not run properly.
The system needs time to
restore service.
Corrective Action
Ensure that the Ethernet cable is securely plugged into
the network port beneath your Deskset and that the other
end is plugged into your office LAN.
Verify that Do Not Disturb is off. Make sure that DND is
not in the top right corner of the Deskset display. Turn this
feature off by using the Deskset Idle screen soft keys.
Verify that Call Forward All is off. Make sure that
is not in the top right corner of the Deskset display. Turn
this feature off by using the Deskset Idle screen soft keys.
Verify that the Audible Ring Delay is not set too long.

VOL+ key to increase ringer volume.
Incoming calls may be directed to a Ring Group that you
are not part of.
There may be non–system equipment connected in
parallel to the telephone line. See

Allow at least one minute for the system to boot up again
after a power failure.
