I don't know about that--at my previous employer, we had 2-3 telephone 
outages per year that largely prevented us from making either incoming 
or outgoing calls for part of a day.  The exact problem varied from 
outage to outage; sometimes it was circuit problems, sometimes it was 
Qwest losing our DIDs, sometimes it was Nortel PBX problems.  Our IP 
connectivity was rock-solid.

Of course, our business was selling rock-solid IP connectivity, so it's 
not an entirely fair comparison.  Still,  I don't have a very high 
opinion of most mid-sized corporate phone systems.  I don't have a very 
high opinion of Verizon or Qwest, either--your switch can be 100% 
reliable, when when the people that program it keep giving away your 
DIDs, it looks a lot like an outage to me.
