This will never be possible in at least one place -- the 516 NPA is within the LATA from the 212 NPA, and a call carried by NY Tel. Dialing without the 1+, however, would lead to some sort of time-out scheme to decide whether one was dialing 516 as an NPA, or just the 212-516 exchange in 212. From 212, incidentally, all out-of-NPA calls are dialed 1+, and all 0+ calls, even within 212, are dialed 0+212+7d. Talk about a full NPA ... Andrew Boardman amb@ai.mit.edu
