Subject: ring back protocol
i live in Malden, Mass. as far as i know, the trunk line i am
connected to is the Arlington trunk line. when trying the ringback #'s
given for the boston area, (98n and the last 4 digits of my number,
n=0,1,2,3 depending on which local telco) some interesting things
happened. 981,982,983 all failed. 980 immediately gave me a series of
tone pulses of approx .1s duration. this would continue unitl i hung
up. i dialed 980 and then the last 4 digits of my phone #, but no
ringback or other indication of activity. BUT(heres the interesting
part) i dialed 980, and when i got the tones, i pulse dialed a '6'. my
phone line immediately went dead. i am not sure if it is back yet, as
it happened early today.
does anyone out there have any ideas as to what is going on?

A while ago I was out at a customer site (a high school)
setting up their dial-in lines. I needed the phone numbers so that I
could check out the lines... unfortunately they were not written on
the jacks so that the students couldn't find out what they were.
I tried the operator like Matthew suggested. The operator
referred me to the Business office for the information. That wouldn't
have been much help either. I tried pursuing it with the operator but
to no avail. It seems that it is now considered a risk to the owner
of the line if they give out the number. Oh well. I did, however,
find the local "magic number" and was able to get the information I
needed.
I don't know what kind of switch Manchester, NH has but that
same number won't work in Nashua, NH. Anyone know what kind of
switching equipment is being used in Manchester and Nashua?

I tried dialing 1(200)555-1212 [Santa Barbara, GTE service area]. Got
"The call can not be completed as dialed. Check the number and dial
again. This is a recording. 805-682". Well, at least they gave me 6
of the ten digits. I suspect that the fake 200 area code may only be
valid in (former ATT) areas.

I tried the 200-555-1212. What I get is the little lady saying...
zero zero zero zero zero zero zero... but the phone also keep ringing.
How odd. Our other favorite method (but it takes time) is to call up
and make a credit-card call. It will show up on your bill next month.
Third, you can sweet talk a friend of yours at the 911 center to tell
you what the ANI readout says.

AT&T's proposal is that the carrier chosen for an 800 call be based on
the number. All current 800 numbers would be assigned to AT&T. If
MCI wanted to provide 800 numbers (and they do), the customer would
get one of MCI's numbers. The other carrier's objections to this plan
is that each carrier would not necessarily get the same set of numbers
in every city. This would prevent their customers from using national
advertising, which they argue effectively makes AT&T the only 800
service. The other carriers want to register the carrier with the 800
number in the AT&T database where 800 number routings are stored.
Since Long Lines developed that database, they are not too enthused
about that idea.
The jist of this is that, since the callee pays for the call rather
than the caller, the callee selects the carrier, regardless of any
choice of the carrier selected by the caller.
