Failed at fax."* ## Applies To - Admin Console - X2 license or higher ## Resolution To resolve this issue, you will need to assign the phone number to a new user, then remove it.

Navigate to **Users**. 3. Select **+Create User**. 4. Fill in the required fields: **First name, Last Name, Email, and Username**. - The information does not need to be valid, we will be deleting this shortly. 5. Under **Services and permissions** select any available service. - If you have no more service licenses remaining, you may need to remove another user's license temporarily. 6. Expand **Voice basic settings** and select the phone number you are having issues with in the **Phone numbers** box. 7. Click **Save**. ### Remove the License 1. Under **Services and permissions** click the **x** next to the service assigned. 2. Click **Continue** when it says **Are you sure?** 3. Click **Save**. 4.
