Sangoma phones have three settings related to backlight. Timeout, active brightness and in-active brightness.
Setting Backlight Options
- You can set the Backlight options using the PBX EndPoint Manager.
- Go into End Point Manager in your PBX and select the Sangoma brand in the menu.
- Click on the template in End Point Manager that you want to modify.
- Click on the Options menu tab at the top
- There are three backlight settings available.
- Backlight Timeout - Sets the delay after last key press before switching to in-active backlight level. Numeric field in seconds - 0 disables timeout.
- Backlight Active Level - Sets the brightness level of the display when phone is active. There are 10 levels with 10 being the brightest.
- Backlight In-Active Level - Sets the brightness level of the display when phone is in-active. There are 2 options, but only the S700 supports the low setting. If set to low, S300, S400 and S500 will use off option.
- Setting a Screen Saver and Backlight Schedule - You can define a schedule during which the Backlight Timeout and the Screen Saver are not active. If you want the phone display to stay active and lit during business hours on week days you can set a schedule similar to the following:
- You now need to update the phone configuration file. The three options at the bottom of the template are:
- Save Template- This will only save your changes into the PBX database. It will not write out new config files for the phones that are using this template as mapped in the Extension Mapping section of End Point Manager.
- and Rebuild Configs- This will save your changes to the PBX Database and will also write out new config files for the phones that are using this template as mapped in the Extension Mapping section of End Point Manager. The phones will need to be rebooted in order to retrieve the changes.
- and Force Update- This will do both the "Save Template" and the "and Rebuild Configs" options above, and it will also immediately update any phones that are mapped to use this template and currently registered to the PBX, with no need to reboot the phones.
