[comp.dcom.telecom] 302+7D in Local Call From 215

I stand corrected by David Tamkin regarding 302+7D without leading 1
in local call from 215 area (Pennsylvania).  It can remain useable,
due to the practice of NOT making prefixes which match your area code
or neighboring ones.  (Such practice, as he pointed out, helps prevent
confusion so that if you hear, orally or in radio ad, your own area
code or a neighboring one, you know there are 7 more digits--not 4.)
