When a call comes into the webphone for the first time, you are prompted to enable or disable notifications. This guide will go over re-enabling them if you had mistakenly disabled the notifications of incoming calls.
Launch Google Chrome and enter chrome://settings into the address bar and scroll to the bottom of the page and select Advanced.
Next you will need to select Content Settings.
The next step is to select Notifications.
(OPTIONAL) - You can manully add https://app.level365.com to the allow list by selecting Add and entering the address.
The last step is selecting the 3 dots next to http://app.level365.com and chosing allow. This will enable notifications of an incoming call.
