PLA's Telephone Network Interface

PLA’s Telephone Network Interface is a phone system that can be accessed by dialing 206-424-8422. Attached to this system are 5 different answering machines that callers can attempt to hack into by brute forcing their way into the remote access features of the machines. If you missed out on the fun of hacking into answering machines in the 80′s and 90′s, this is your chance to see what it was like. Here are the machines currently hooked up to the system:


ITT 9110 Answering Machine RCA 25250RE1-A Answering Machine
ITT 9110: RCA 25250RE1 (This is a lie. I need to update this.):
GE 29875GE1-B Answering Machine GE 29876B Answering Machine
GE 29875GE1-B: GE 29876B:

If you click on the model numbers above, you’ll be taken to a Google search for the answering machine model numbers where you can sometimes find an online manual for the machine which will tell you how the remote access features work and sometimes will even give you the default code for the machine. Remember, though, that half the fun is actually figuring all this stuff out for yourself, so give that a try before cheating and looking up the manual.

Once you’ve accessed a machine, you are welcome to do any crazy things you want to them. Delete all the messages, try to lock other people out, and whatever else you can think of. Have fun! New machines will be added. I’m planning to eventually hook about 10 machines up to the system at a time and I will rotate new machines into the mix occasionally.


OTHER TNI THINGS

The phone system is running Free PBX on Asterisk and is available 24 hours a day. The 505 number is a paid number that costs around $8/month through Flowroute and it allows 2 simultaneous outside phone connections. I’m hoping to find a SIP service that allows more simultaneous connections, but doesn’t cost too much more, so if you can recommend any good providers, either contact RBCP or leave a comment on this page. The 425 number is a Google Voice line and it’s free, but it only allows a single connection at a time. The 206 phone number is the newest addition to the system and it’s provided by IPKall. TheN claims this has a buttload of available channels for incoming callers, so if that’s true I will most likely phase out the 505 and 425 numbers.

The phones are connected via Linksys PAP2T phone adapters. Each adapter supports 2 separate phone connections, so I will need 3 more of them to reach my 10 answering machines goal. Lots of thanks goes to TheN from afterthetone.org for recommending these adapters because they’re a lot cheaper than the PCI cards I’d planned to purchase before.

If you’d like to donate old answering machines to this project, you can mail them to Phone Losers of America, P.O. Box 465, Albany, OR 97321. Keep in mind that the cost of mailing an answering machine will probably be $5 to $10, or maybe even more if you use a comically oversized box to send it in. Use a real return address if you’d like a PLA sticker mailed to you. Make sure your machine has remote access capabilities and a power supply. This project could also benefit from a 4 or 5 port ethernet switch since I’m completely out of ports to plug these PAP2T adapters into, so if you have one of those lying around…


CHOOSE YOUR OWN ADVENTURE

PLA’s TNI project has several other plans for this Asterisk machine. One is a “choose your own adventure” style of story telling, which will use a telephone keypad to make your choices in the story. Has this been done anywhere before? Let me know if it has and maybe I can steal ideas from them. I know story telling probably wont appeal much to the type of people who will be calling into this machine, but it’ll be an easy project to set up so I’m definitely going to put a couple of them together soon.

A slightly more ambitious goal is a public “voice BBS” which will allow callers to listen to a series of voice messages and then append their own message to it for others to hear. The Defcon Voice Bridge from the 1990′s had a system like this and it was a lot of fun. 2600′s phone system also had one and probably still does if it still exists. I’m fairly new to Asterisk and will have to learn how to write modules for FreePBX, which I’m certain I’ll be able to do but it may take awhile for me to have some time to start on that project. I’d hoped that a module like this already existed, but I haven’t been able to find anything similar to it yet. If anyone knows of a system like this already available for Asterisk, please let me know.

I’m open to ideas for this thing. Except for a voice bridge since that would eat up all my incoming phone lines. If you have any ideas or comments about this project, you can contact RBCP or leave comments below. You can also discuss this project on the PLA forums.
