Once more into the telephony breach, dear friends...

By Andrew Pollack on 07/04/2005 at 03:31 PM EDT

In 1993 I used Phone Notes with a Natural Microsystems 4 port voice card to create a voice interactive sales tool for company here called "The Maine Idea". At the same time I set up my own office voicemail system with the same Remark product. Its been 12 years, and here I am back to telephony.

Last week, I created an entirely software based voice interactive system designed to be used in our small fire department to allow firefighters outside the range of radios to listen to the radio traffic using a cell phone when they've received the text-page sent out by the automated tone-alert listener. The system handles 4 inbound lines at once, and even records the traffic with space removed so that later this week it will support a "catch me up" mode.

Total cost:

Server Hardware: $400
4 Inbound Lines: $11/mo (unlimited inbound)
Scanner: $30 (used)
Operating System: $0 (linux)
PBX Software: $0 (Asterisk)
Sound Card Software: $0 (ALSA)
Text to Speech: $0 (Festival)

I'll write some more in the way of "HOW-TO" later this week.

Thanks to the fantastic work by John Curtis and his team, the node.js integration with Domino is going to be getting a rich security model. What we know is that a user's authorizations will be respected through the node.js application to the Domino server -- including reader names, ACLs, Roles, and so on. The way ......
