I live in a rural area with maybe 3000 people in the town.
I went to a payphone at a gas station in town to play around with it.
I dialed the MCI ANAC (1-800-444-4444)and it read me the ANI.
I then called the number I received not expecting anything to happen.
The payphone started to ring, I was like wow this is pretty cool.
I was hoping to be able to talk once I pick up handset on the payphone but I keep getting this error
"Error 48, Error 48, Error 48, (Beeep)" and I get disconnected immediately.
I was wondering if anyone knows anything about the error or anything.
Is it a misconfiguration? Also do a lot of payphones allow dialing in?
I don't know what kind of payphone it is.... COCUT? or whatever else there is.
I plan on reading some stuff on what a COCUT is and how to tell what type of payphone it is and why, just haven't got around to it yet.

I just started to venture in playing around with things in telephony, so I'm clueless.

Do you mean COCOT (customer-owned coin-operated telephones)?

Basically its a payphone (correct me if i'm wrong) owned by private companies. For example if I found a payphone not by BT in the UK it would be a cocot. Not sure about America but if you've seen a non standard pay phone it would most likely be a colcot.

I cant help too much, my phreaking skills suck. Just know what i've managed to pick up from the early episodes of off the hook :tongue:

COCOT - coin operated customer owned telephone... or was it customer owned coin operated telephone.. either way... any payphone not owned by the RBOC (verizon, etc) would be a COCOT...

most payphones do not accept incoming calls...

some payphones do have a modem inside of them that the owner can call up from a remote location and access certain information about the phone like how much money is in the phone...

i would assume that the error is coming from the payphone itself.... but the only way to really find that out would be to connect a butt set to the dial tone before it enters the payphone pedestal and call into the number

It sounds like a payphone made by IntelliCall. It would be a Protel, as well. I've had the same thing happen to me before, it's just the software's way of blocking incoming phone calls. It does the job, huh?

Yeah, COCOT, my bad.

I do get modem tones from the phone if I do not answer after the second(it might have been first) ring.
I might try dialing it up. I wonder if it will log my CPN?
Is there a stealthy way to approach this?

The modem is because the owner of the payphone calls up the phone with a modem and has software that gives information on daily earnings, price info, and various configurations. When I was younger, my dad owned a majority of the COCOTs in Oklahoma City. The software was pretty tight.

The payphone itself won't, but it's most certainly in the switch logs somewhere. If for some reason you sodomise the COCOT and the company that owns it wants to take action against you, they could easily subpoena the LEC.

Take a look at this, it pretty much covers most COCOTs out there. You'll find a few other kinds out in some areas, particularly rural ones where the phone company fits their phones with COCOT boards, but they're pretty rare.

For the hell of it, here's one of the ones they don't cover. My guess is it's an old Elcotel board.

The ANACs I try calling are a dead giveaway this dates a few years back. I got a little frustrated with the phone eating my change whenever I got an error recording without SITs, so I moved onto an ACTS phone almost immediately after.

Anyway, as for the payphone you found, that sounds like a Protel model - a fairly modern one at that. Here's a manual for the model I'm thinking it is. The error cause code near the end of the PDF should tell you why it intervened.

EDIT: huh, DNS isn't working. Fixed.

Thanks, you guys have been very helpful!
Yeah, that phone definitely looks very similar to the Protel. I haven't had a chance to go back yet but I will here soon.
As for ACTS and SIT do you have information what these things do (these are new terms to me)? All I could find are Wikipedia entries that really didn't help.

SIT = Special Information Tones the do-de-do before an error recording... http://www.sandman.com/sounds/sit.wav

ACTS = Automated Coin Toll Service

Like I said I found the wiki's because I searched for the acronyms.
I understand SITS, pretty self explanatory, but I don't quite understand ACTS.
Wiki gave this under the TSPS entry:
Automated Coin Toll System (ACTS)
Debuted in Phoenix, Arizona in 1977 the Automated Coin Toll System or ACTS was an addition to TSPS which provided an automated way to perform charge advisory and toll collection of coin paid calls - reducing the need for operator involvement. The ACTS sub-system of TSPS handled the automated voice announcements ("Please deposit 50 cents for the next 3 minutes" (all voiced by Pat Fleet)) and worked with TSPS for coin deposit (start of call) coin collection/coin return (at end of call

I thought that was kind of a vague unless that's really all it does.

EDIT: I think I may have found something

i am not the original person who brought ACTS up... but perhaps what he was referring to was teleco owned payphones as opposed to COCOTs.... at least that is what i think...
