Phil: You have go tto be shit'n me? This vile pile of crap is callign your home phone? If it were me, I would install a phone recorder record all of his calls. Turn that over to the phone company, they frown on such things. If that didn't work, I would be burning some frequent flyer miles and resolving things in person. Calling someones personal home over an internet pissing match is way out of line and should be taken care of ASAP.
A gun is like a parachute. If you need one, and don't have one...
you'll probably never need one again.
