Hello, we have various Grandstream models in our office.
In 2 of our GXP-1628 phones and in 1 of our GXP-2170 phones the red light at the upper right corner keeps flashing. I rebooted the device, I disabled voicemail, I checked all the unanswered calls. I also entered the device menu and there is no possible way to delete or completely remove this feature.
I am desperate. Does anyone have the answer? It is pretty annoying and irritating for the eye to see this light going on and off while working.
Thanks in advance
