Even on non-reporting probation, it doesn't matter at all that he wasn't able to reach his probation officer by phone - he was supposed to keep his probation office appraised of his address. He can do that in person if necessary. You know what else? Paper, pen, envelope, postage stamp - it's nobody's fault but his own if he failed to inform probation of his current address and phone number.
You want suggestions for... what?
