I am highly confident.  We've had no problems recieving faxes as best I can determine, and the lines certainly sound perfect, all the time.  Predictible, since the lines arrive at the building via OC-3, so no old corroding copper here.

The "9" in-front of the number should be a clue.  In fact this goes through Verizon's PBX switch (so don't bother suggesting we test it).

Yes.  My testing has included numerous data connections to/from these lines, at high speeds, without any sign of problems.
