Andre,

I agree with your opinion that the fax machine is most likely the cause;
however I don't think DSL noise would stop somebody from accessing the
phone line externally.  The latest butt-in test sets that the telephone
company technicians use have built-in filters and noise is not a problem
with them.

Also, while the telephone logger is a good idea, won't a logger log
calls dialed from outside of the church too?
