I have a local provider who requires 7 digit dialing for local (in the 
same NPA) on both a PRI and a SIP trunk.  10 digits give an error.  We 
are in a funky area where there are a couple of additional TN ranges in 
another NPA that are considered local, those require 10 digits.  All LD 
requires 11 digits.

Personally, on the systems I administer, they have all been 10 digits 
for a decade plus at this point.  SIP, of course

With Gratitude,
