How to Override Do Not Disturb and system volume
Unfortunately, right now, Apple’s APIs do not allow our app to override Do Not Disturb mode or the phone volume on iOS. If this changes in the future, we can investigate ways to implement the feature to override phone volume for push notifications.
The current workaround to have an OnPage alert override the Do Not Disturb or phone volume is to have the alert delivered as an IVR redundancy call using an Emergency Bypass. This can be done on iPhones with iOS 10+ by following the steps below:
Login to the OnPage Dispatcher portal
Click on the Contacts Tab
Double click to edit contact
Add the contact phone number in the “Phone number” section
Uncheck “Secured Messaging”
Check the “IVR” box and from the drop-down menu, select “Default”
Create a contact in your phone called “OnPage” and add the phone number 855-266-7243
Select Add to Favorites
Click on Edit in the top-right corner
10. Click on Ringtone
11. Enable “Emergency Bypass” and click Done
12. Profile should now look like this:
