Still no possibility to turn off “missed call” indicaton?
Customers often do not agree with a blinking red button.
It´s nice that the backlight can be turned off for missed calls, but the red blinking button under the screen isn´t also a great thing.
Especially when the lights are turned off and it should be dark in the room the small blinking red button disturbes absolutely.


This is user configurable feature. You can disable this notification feature by going to touch UI:

“Settings” ==> “Display” ==> “Enable back LED indicator”, just slide OFF the LED indicator, then the missed call or alarm will NOT light up the LED.

Thank you for using Grandstream Access Control Products.


I know, i know. I already wrote that it disables the “BACK” LED indicator.
But there´s no way to disable the indicator at the FRONT “home button”
This one blinks red anyway…
If I don´t want do indicate missed calls in any way, this also should be possible.


I see. I will pass your feedback to engineering team for consideration. Thanks!
