Contact ID dialer capture using a PIC16F628

Quick showing of a little dialer capture module I am working on, using a PIC16F628 microcontroller and a MT8870 DTMF receiver. It connects to an alarm panel's telco terminals, and emulates an alarm receiver. It currently supports Contact ID, Express 4+1, Express 4+2 and Ademco High Speed formats. This was just to test the dialer capture side, but I'll be remaking this board with an ethernet interface and eventually using it to transmit the captured events over IP.
The panel I was using to test is a GE Simon XT, and the loud fan noise in the background is from an HP power supply.

That’s actually kind of cool, where numbers can be turned into messages

[@hackmiester1337]

Have you published the program? Very curious.

[@Decofanblade]

Maybe I sound ignorant by saying this but this is a nice module for the protocols. Very Creative!

Hi, love you project, could you provide mor information about ?

[@alanaquinojr]

Hi. Great work. Could provide more details?
