Your hypothesis would be correct  ......... EXCEPT in this situation
we are dealing with two different "Telephone Companies"  (I never did have
a "Telephone Company" as Rochester was never serviced by an ATT company. :-)
New York Telephone Company utilizes the 716 (without the "1") to access the
Rochester Telephone Company circuits for local calls from the 315 area
code. Ironically, Rochester Telephone does not use the "315" area code to access
the "315" numbers that are local calls from Rochester.
To put it simply,  I dial 999-9999 to get (315) 999-9999, but they have to
dial 716-888-8888 to call me back.  (Adds a little more confusion!)
