If you are on a call and the display suddenly shows “Discovering...,” the network connection between the telephone and the call server was interrupted, but your call stayed connected. The telephone automatically starts to re-register with the call server, but until re-registration succeeds, you do not have access to switch features and functionality such as Transfer, or to administered Feature buttons.

If you cannot resolve the problem based on the message received, contact your System Administrator for resolution.

See “Phone does not activate after connecting it the first time.”

Check all lines into the phone to ensure that it is properly connected.

Check the power source to ensure that your telephone is receiving power.

Perform the following Test procedure: with the telephone idle (on-hook), press and release the Mute button. Then press the following numbers on the dialpad: 8 3 7 8 # (which stands for TEST). The display should indicate the self-test has started, then report if the test was successful or failed. If nothing appears on the display, and the phone is receiving power, your phone might need to be replaced.

If these suggested solutions do not resolve the problem, reset or power cycle the phone with your System Administrator’s assistance.
