My last job used https://github.com/opserver/Opserver which had a pagerduty tab. Nice being able to see who was the on call and have instructions for when/how to page out.

It also has a "take on call for the next hour" button, which (for logged in users that matched a pagerduty user) would create an override for the next hour. Really handy when you are starting a change window and don't want to risk waking up the on call.
