[VoIP] Old DT, Busy & Reorder on 366

Hi gang,

I FINALLY wired up the board with the ISD digital recorder chip with the 
"old" 600/120 tone in it and modified my microcontroller interrupter to 
dial with gating said tone at 60 IPM and 120 IPM for busy and reorder and 
this evening have it semi-permanently wired into the switch.  A tip of the 
test set to Jayson Smith for providing me with the 600/120 sound file that 
I played from the computer into the chip.

Since I have the open audio path patch in my * box you can hear the DT when 
you dial into my switch and can access the busy any time at 366-3214, and 
reorder at 366-34XX.

This is a work in progress, I find that the audio levels aren't all the 
same so that will require some tweaking.  Though, seems I recall the EM 
switch that used to serve my house as a kid had progress tone levels all 
over the place.  I also have to re-work the mounting of the microcontroller 
board on the switch frame to accommodate the board with the recorder chip, 
so for the moment the boards are just lying in front of the switch...

Whatever, my little beast now sounds a little more like an old switch.

Next on the list is to get a ringback tone of some kind going with a 
similar process.  No telling when I'll get to THAT.  :-)

Doug.
