[VoIP] Numbering - existing use of 311

Maybe I have a southern California bias or something, but I never
really understood the whole "1+ Toll Alerting" business. I realize
some people love it, but I always thought it was silly, and now
that long-distance is down in the 0-4 cents per minute range, is
it really that big of a deal?
Correct me if I'm wrong, but wasn't 1+ dialing introduced to
disambiguate out-of-npa calls when generalized (from NNX to NXX)
office codes were first assigned back in the early 70s? Back when NPAs
were all N0/1X and office codes were all NNX, there were no O.C./npa
collisions, so all calls could be dialed as 7D or 10D without
ambiguity. So the idea of 1+ = toll alerting seems like an artifact,
not something by design.
Living in Los Angeles, where area codes are quite numerous, people
have generally started just dialing 1+10D for all calls. Given that,
it seems to me that the 1 is now just anachronistic baggage, so for
my systems, I've dropped it. I just use 10D for all calls. You
can use 7D but there's a timeout.
The telcos still require the 1, however.
Also, in 310, which is scheduled for an overlay, 1+10D is now
mandatory on *all* calls. I understand the rationale here is that
since the CLECs will be the ones primarily getting assignments in
the new area code, the CPUC wanted to level they playing field by
requiring 11D, thereby eliminating the preferability of 310 office
codes.
But anyway, meh on 1+ toll alerting, I say.
