I've installed something called Essential Calls, but the description indicates that they haven't been able to get it to work with Lollipop yet.
When I google what I want to have done I get articles like these but none of the features/menu options they talk about appear to be present on my AT&T Note 4 running Lollipop.
Android has Essential Calls. I imagine iOS has an equivalent.
I believe this might work.
