Important
Phone Apps are designed to work only with Sangoma IP Phones.
Press the DND button on your phone.
From here you can see the Enabled field is set to "No."
Pressing the Change button will change the Enabled field to "Yes."
On phones that support a BLF light with the button, you will now see the DND button is red, informing you that DND is enabled.
On phones that support center screen notifications, the status of "Do Not Disturb active" will also display any time DND is enabled, as shown below.
