Please recommend an application for recording calls and blocking spam among smartphone applications

I need the following two functions among the smartphone applications.

Recording calls
Block spam

Please recommend an application that supports these functions~

You may recommend one of each.

I hope there's something that works for both, but there's no such thing, right?
