Ooma cordless IP phone is not displaying the extension name

Last Updated: July 21, 2025

If your cordless Ooma IP phone is not displaying the extension name, the following steps can help you troubleshoot the problem:

  • Confirm that the IP phone is assigned to a user by following the instructions in this article.
  • If the device is already assigned to a user, restart the phone by long pressing the power (hangup) key and then confirming that you want to shut the phone down. Long press the power key a second time to restart the phone.
