Troubleshooting

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).

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.
