You're referring to "common carrier" status, I think.

This isn't exclusively restricted to phone companies, but that's the way 
it is right now.  I think it may also apply to non-voice carriers that 
sell circuits.  I'm pretty certain that it does not apply to ISPs.

A common carrier is not allowed to monitor/filter traffic on customer 
circuits.  They also can't be held responsible for the traffic on those 
circuits.
