Telephone "Automatic Intercept System" with a microcontroller

You're going to have to ignore my stutter throughout this video, but here's one of my recent projects. I have recreated the Automatic Intercept System using a PIC microcontroller and a flash chip. I have tried to get it pretty close to how the original AIS sounds, but it also supports ANR and several other messages I didn't show here. Basically the data lines of the flash chip are connected to a R2R resistor DAC, and the address lines are connected to the PIC. The PIC answers an incoming call, receives and parses incoming DTMF tones from the voice gateway to determine what message to play, and then pieces together the right recordings stored in the flash chip to generate the message telling you why your call failed. It is all PCM stored in 5-second chunks in memory, all the phrases have a start index and a count of how many chunks it takes up, the PIC sets the address to the starting address and then increments it on a 8khz interrupt until it reaches the stopping address. Works surprisingly well to be honest, I plan to use this technique in the future for other telephone related things that need to play voice prompts. The 884-XXXX block in the TandMX telephone collectors network is directed towards my voice gateway here, so if you want to hear this announcer you can call a random unallocated number on that block and it'll reach it. Once Jaiden (Hi-Smart Alarms) makes a video on their very similar AIS, no we're not copying each other... We've both been working on these in parallel recently, just I used a PIC and Jaiden used an Atmel. We're pretty much the same mind, but in two separate people lol Also yes I know its been a while since I have made any videos, I have a lot of interesting and rare alarm panels to show, and I do plan to continue my Motorola 6809 project eventually. Just with work and other things my motivation to work on things other than software has been pretty low.
