Suggested Resolution
Various potential network problems
may be causing the problem.
Contact your LAN Administrator
with as complete a description of
the problem as possible.
Room acoustics may be causing
problems. Clear the area around
the telephone's speaker; if this
does not resolve the problem, use
the handset.
If the "Ringer Off" feature is
programmed on a feature button,
that feature is engaged if the button
is darkened or shaded; reactivate
the ringer by pressing that feature
button.
Set your ringer volume to a higher
level using the Up/Down Volume
keys.
From another phone, place a call to
your extension to test the above
suggested solutions.
Ask your System Administrator if
your Speakerphone has been
disabled.
The 4630 display screen takes an
hour or so to completely warm up;
