What is the penalty for prank calling? Does the police even care?

So me and my friend decited to prank call a boy who was bullying her last year for revenge. It was a simple prank call saying "Your dad is cheating on your mother with my mother! You're father is ruining my family." Just to scare him a little. It was just a funny prank call and I didn't think he would even take it seriously. An hour later, his mother called and told us she was going to get the police involved, we lied and told them we got the wrong number and we texted him saying we got the wrong number too and he texted our number and said "Okay goodbye weirdo"
His mom told us she was in the law enforcement and we started getting scared if she would track us down or not. I know we went a little too far this time but we did not expect this to happen, it was just supposed to be a funny revenge prank call thing, and I never thought this would get out of hand. So the question is, is there a penalty for prank calls? If so, what is it?

He sent us a text saying that his mom called the police, would the police even care or do they have other things to worry about, like more of a serious crime? It has been 2 days since the call and we left them alone since then. Would they have done something by now?

What a spiteful thing to do. They will let you worry for a while.
