ZoIP/Zasterisk & the great undergroup empire

Wednesday June 6th, 2007

Digium noticed ZoIP!

"Game Play

Do you miss the good 'ole days of text based computer games? Or maybe you would like to find a way to use your time effectively while waiting on hold. Simon Ditner, a speaker at the IT360 conference in Toronto, recently described how you can play games over the phone system for both fun and for points.

Ditner recently created a game called Zoip (a blending of Zork and VoIP) which brings back to life the original Infocom game Zork. Zork, a text-based game, was originally a difficult game which relied on your imagination and ability to solve word puzzles in order to succeed. Zoip utilizes Asterisk coupled with speech recognition and text-to-speech technology to play the Zork game."

I gave another talk on ZoIP at IT360 in Toronto this past Wednesday. If you're looking for the slides to that talk, they here here:

There was also a writeup in Eartheweb IT Management on my talk.

I spoke at Astricon 2006 in Dallas, Texas today. If you're looking for the slides, there are two parts:

I tested ZoIP with Inform 7, outputting in the z5 format, and it appears to mostly work. I created a simple office and was able to navigate around a 4 room. Test it out for yourself, and let me know how it goes: Inform 7

Update: You will have to edit 'Asterisk/Games/Zork/ZIO_Asterisk.pm', and change $speaking = 0 to $speaking = 1, or alternatively, add your serial number to the "if ( $string =~ /840726$/ ) {" regex to skip over reading the zmachine version number, and such, when the game first starts. (Thanks to Paul C. for pointing out that it didn't work as advertised ;-) )

I gave a talk on sprec and ZoIP to the Toronto Asterisk Users Group using the Lawrence Lessig style after being inspired by Dave Gray and Dick Hardt. You can download it if you like. It was well recieved. I'll likely polish it up and present it at Astricon next month.

Version 0.2.1 has been released. I discovered that Zork isn't abandonware -- Activision owns all the copywrites, so I've removed it from the distribution.

ZoIP - a telephony/text adventure bridge for Asterisk and Infocom games

ABOUT

ZoIP (formerly Zasterisk) implements a Rezrov ZIO object, allowing a user to communicate with a Z-Machine via telephony devices.

I was tinkering with Asterisk and the Festival text-to-speech engine, and wrote some short Asterisk::AGI scripts to read back live weather reports. After that, I thought I needed something more interactive to work with...

Then I had a flashback to 1996, first year university, standing in the C & O club at the University of Waterloo, where someone had just pulled out their US Robotics Palm Pilot and started up Zork. A couple of hours later, after a quick trip to the campus computer store, I was playing Zork in the palm of my hand!

Now Zork is back! Listen as the eerie voice of Festival takes you into the Underground Empire, and marvel as you explore this world with your dial pad, unlocking the secrets within! What will Asterisk bring us next? The future is open!
