-On 01 calls, at least in Chicago, the credit

-I'm not sure why it didn't work for the Moderator; I just tried 01+
-from an exchange in the Chicago Loop area and was presented with the
-"bong" and was able to enter a calling card number.  TSPS has a
-database of which phones have TT service; the bong is presented to
-those phones, and not to phones that don't have TT service, but you
-should see the same behaviour on 0+inter-LATA and 01+overseas.

-[Moderator's Note: Well, *when* do you enter it, after the
-international number has been dialed as you would on a domestic call?
-With international numbers of variable length, how is it known where
-the international number ends and the credit card number begins? Do
-you enter the international number, then hit the pound to terminate
-the dialing and then enter the card number following the bong?  On

I'll comment on a few of the above claims based on personal experience,

On 01 calls in almost all cases you will be electronically requested
for the card number with the bong. This all assumes your long distance
carrier is AT&T. It may be different for others. This does not matter
if you are set up for TT or dial pulse. I have only Dial Pulse at home
and I always get the bong. (At which time I flip the little switch on
my phone and touch tone in my card number.)

(Yes I do do this from home sometimes to charge to different number).

The digit collector mechanism has a timer which will time out when no
more digits are entered (normally this is about 5 seconds). This is
how the switch knows to start collecting the credit card number
instead of the number to call. You may also hit the # key, which will
terminate the number immediately.

This may not work for the moderator, since Northwestern University has
their own "goofy" PBX system, which allows and doesn't allow some
strange things. (My wife is a graduate student there, so this is based
on her experiences.) Also if the default LD carrier is not AT&T, this
may be the reason why the "bong" is not heard.

[Moderator's Note: But I don't use NU's phone system in any way,
except to call into the dialups ... I am served out of the
Chicago-Rogers Park office. But international calls like that are rare
for me: Either I dial direct or I call via my employer's
call-extender, and bill it to the office that way.  That's why I
reallt didn't know.  PT]
