How about, if he makes calls as part of his job, ring home first thing, let it ring twice and hang up?
That way you know he's arrived OK, it'll cost nothing, and shouldn't appear on company call logs.
It's what I used to do with my mum BITD when I was 8, off on the bus to a mate's house miles away in Basingstoke, and phone calls were really expensive.
All the best,
He cannot ring out either, funny his manager has had to divert all calls in order to divert outward/ inward calls so now he has to deal with all the calls which is causing him problems of his own so it might not be for long just to make a point.
You can't buy happiness but you can buy a bike and that's pretty close
