Suggested Solution
Ensure that the cords into the phone are
securely connected. Note that there might
be a slight operational delay if you unplug
and reconnect the phone. Reset or power
cycle the phone with your system
administrator's assistance.
Contact your system administrator if these
steps do not produce the desired result.
Use the Up/Down Volume keys to set your
ringer volume to a higher level. Verify that
the "Do Not Disturb" feature turned off,
using the Select button and the arrow keys
to scroll down to that item. From another
phone, place a call to your extension to test
the ringer volume.
Verify the procedure and retry. For certain
features, you must place the phone
off-hook first.
Contact your system administrator if this
action does not produce the desired result.
Your telephone system might have been
specially programmed for certain features
applicable only to your installation.
Contact your system administrator.
