Troubleshooting
No Dial-Tone
Verify power is correctly applied to the
SoundPoint
IP 600 SIP phone:
®
• Check that the display is illuminated.
• Make sure the LAN cable is inserted
properly at the rear of the phone
(try unplugging and re-inserting the
cable).
• If using inline powering, check that
the switch is supplying power to the
phone (contact your System Adminis-
trator).
No Display, Incorrect Display, or Bad Contrast
Verify power is correctly applied to the
SoundPoint
IP 600 SIP phone:
®
• As "No Dial-Tone" above.
Verify contrast adjustment:
• Follow the instructions in this User
Guide to readjust the contrast to a
darker level.
• Reboot the phone to obtain a default
level of contrast (follow the instruc-
tions in this User Guide).
No Ringing
Verify incoming ring setting and volume
levels:
• Adjust the ringing level from the front
panel using the volume up/down keys.
• Check that ring type selection is not
Silent Ring.
No Audio on Headset
Verify correct connections:
• Ensure the headset is plugged into
the jack marked Headset at the rear
of the phone.
• Ensure the headset amplifier (if pres-
ent) is turned on and/or the volume
is correctly adjusted.
Verify if dial tone is present on any other
audio paths:
• Switch between handset, headset (if
present) or hands-free to see if dial
tone is present on these other paths.
• If dial tone exists on one of these,
connect a different handset or head-
set to isolate the problem.
Verify successful outbound or inbound
calling:
• Place a call to the phone under in-
vestigation - check that the display
indicates incoming call information.
• Lift the handset. Ensure dial tone is
present and place a call to another
extension or number, check that the
display changes in response.
Verify successful outbound or inbound
calling:
• As "No Display" above.
• Check same status of handset,
headset (if connected) and through
the hands-free speakerphone.
• Ensure that headset is compatible
with the phone.
