Our conversations generally last about 30 seconds.  I can never tell it is him calling to I often end up answering...he is homeless so uses a different phone all the time.  When I suspect it's him I definitely don't answer.  I tried talking to the police about a restraining order, but in order for him to be served he has to have an address, and he moves from city to city every week or so.

Belrose, I have no idea what works with these kids.I have tried everything I could come up with when mine was living at home...the only way to deal with them is to get rid of them.  If you can prove somehow that he is a danger to the other kids you might be able to have children's services take him out of your home...that's how we moved ours out at 14.
