By default, the connected status is mapped to the color red, but Snom 710 and 715 models have only green LEDs.

That's why we introduced the setting led_colors_used_for_green_only_leds.

In order to have BLF led on in the connected status, you must add the value "red" to this setting. 

To perform this action you have two methods:

• Use an HTTP request:

  http://Phone_IP/settings.htm?settings=save&led_colors_used_for_green_only_leds=red green

• Adding the following XML tag into the provisioning files

  <led_colors_used_for_green_only_leds perm="">red green</led_colors_used_for_green_only_leds>
