Configure Display Settings for a Provisioned Phone

When you provision an IP phone (Internet Protocol phone: a desk phone that connects over your data network instead of a traditional analog line) through Cloud Voice, you can control how its screen looks and behaves without ever touching the handset. From the phone’s settings page you can assign a wallpaper, set a screensaver and boot logo, adjust how long the backlight stays on, and decide whether the screensaver clears when a monitored line changes state. Doing this centrally means every phone can be styled consistently and reset remotely, which is useful when the device sits at a customer site you cannot reach. The steps below use a Yealink T54W as the example; the same workflow applies to other supported models.

Requirements

Your system must be running Cloud Voice firmware 84.20.0.21 or later.

Caution

If your firmware is older than 84.20.0.21, the display fields described here may not appear. Update the firmware before you start, otherwise the options will be missing and the phone will keep its current screen.

Before you begin

• Upload the image you want to use. See Upload an Image File for Auto Provisioning.
• Connect the phone to the PBX (Private Branch Exchange: the phone system itself) and bind it to an extension through auto provisioning. Depending on how the phone reaches your system, follow one of these guides:
  • Auto Provision IP Phones Remotely via RPS Method
  • Auto Provision IP Phones Remotely with Proxy

Procedure

1. Sign in to the PBX web portal and open Auto Provisioning > Phones.

2. Locate the phone in the list and click the edit icon next to it.

   

   The Phone settings page for the extension that owns the device opens.

3. Scroll to the Preference section and set the display options you want.

   

   • Wallpaper: Choose one of the images you uploaded to use as the background.
   • ScreenSaver: Choose an uploaded image to display while the phone is idle.
   • Backlight Timeout (s): Enter how many seconds the phone can sit idle before the screensaver starts.
   • Exit Screen Saver when BLF Status Change: Decide whether the phone wakes from the screensaver when a monitored line changes state.

   Note

   BLF stands for Busy Lamp Field: a key on the phone that monitors another extension and lights up to show when that person is on a call. Turning this option on wakes the screen the moment a monitored colleague’s status changes, so users can glance at availability without pressing anything.

   Tip

   The exact fields shown depend on the phone model. If an option (such as a separate boot logo field) does not appear for your device, that model does not support setting it through provisioning. Only images you have already uploaded appear in the wallpaper and screensaver lists, so upload them first.

4. Click Save.

5. Reprovision the phone so it picks up the new display settings.

   

   1. Click the reprovision icon next to the phone.
   2. Click OK in the confirmation dialog.

   Caution

   Saving alone does not change anything on the handset: the new look is applied only after you reprovision. Reprovisioning makes the phone reload its configuration from the PBX, which can briefly interrupt it, so do this while the phone is idle rather than during an active call.
