What I understand about the various long distance companies would lead
me to believe that 950/800 access is different from 10xxx. 950/800
calls require you to have an account with that long distance company
and have one of their calling cards. 10xxx calls can be billed to the
telephone you are calling from.
Therefore most LD Companies need both 950/800 and 10xxx. In the case
of AT&T it would be the same calling card since the BOC data base is
shared with AT&T (When you ask for an AT&T card they ask the BOC for
the number). I don't know why the other companies can't check their
calling card data bases like AT&T checks their Universal Card database.
When 10xxx started here you had to use the card from that company.
They could say something like press 1 to use you Local Phone Company
Calling Card press 2 to use your MCI Card or whatever.
Now the problem with the Call Me card is that some LD companies other
then AT&T do not check the type of card and will accept it for any
call. The good thing about 800 personal service is that it is
available from phones were there is blocking of 950 and 10xxx dialing.
There is no need to have touch tone (If you don't have tone you would
have to read you card number to the operator and people could overhear
[Moderator's Note: Actually, with 10xxx service, neither 800 or 950 is
required. After the 10xxx of choice is entered, you can then dial
using 1+ or 0+. Everything 950/800 can do, 10xxx can do better. In
addition, 10xxx allows billing to the phone being used, something you
do not get with 950/800. The main reason these guys do not want to
have 10xxx available is because (a) some people would actually use
AT&T thus depriving the phone operator of a commission structure they
like better than what AT&T will pay, and (b) they would have to
program their switches to disallow 'sent-paid' calls over AT&T (if
that was their choice) while still allowing 'sent-paid' on the carrier
they did want to use. I'd say that's their problem. 10xxx is the
method preferred by AT&T. PAT]
