No, a static IP address isn't likely to solve the real problem.

What's probably happening is that the transitions on the line are causing
havoc with the DSL, and the DSL modem is restarting the session.  This is
not supposed to happen, but sometimes does.  Have him call Bellsouth and
tell them his Internet stops working when he picks up or hangs up the
phone.  They'll most likely get it fixed.
