Troubleshooting

No Dial-Tone

Verify power is correctly applied to the SoundPoint® IP 500/501 SIP phone:

Check that the display is illumi- nated.

Make sure the LAN cable is insert- ed 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 Administrator).

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.

No Display, Incorrect Display or Bad Contrast

Verify power is correctly applied to the SoundPoint® IP 500/501 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 instructions in this User Guide).

Verify successful outbound or inbound calling:

Place a call to the phone under in- vestigation. Check that the display indicates incoming call informa- tion.

Lift the handset. Ensure dial tone is present and place a call to anoth- er extension or number. Check that the display changes in response.

No Ringing

Verify incoming ring setting and volume level:

Adjust the ringing level from the front panel using the volume up/ down keys.

Check same status of handset, headset (if connected) and through the hands-free speakerphone.

No Audio on Headset

Verify correct connections:

Verify successful outbound or inbound calling:

• As “No Display” above.

Ensure the headset is plugged into the jack marked Headset at the rear of the phone.

Ensure the headset amplifier (if present) is turned on and/or the volume is correctly adjusted.
