[asterisk-users] fax - sound/tone - dealing with SPAM

[Joseph]

I receive several calls from this scamer: Senior SafeAlert
It is an automated call and they keep rotating their caller ID so it is harder to block them.

Does asterisk have a "fax" sound tone? If I block their number and play "fax" tone/sound maybe they will remove me from their calling list.
I've tried to call them but nothing helps. 

Any better ideas? They keep calling sometimes few times a day.
