Number is on my phone repeatedly...don't know who it is from

I receive so many bogus calls from this number. Is there any way this could stop?

This is a phone system called all stream. Usually unsavory people in unsavory worlds use it with a remote IP phone that is used to place calls monitor calls on a 3way call. The individual remains untraced using GPS so law enforcement has trouble getting a fix on caller origin

I picked up but there was no one there.  robo-dialer?

picked up but no one answered
