Yes, those are the addresses for the individual number sounds on the isd25120.
This section works sometimes, allow me to explain.

I call the pic and the phone answers.
I press any button and the welcome message plays.
I start entering my password (1,2,3,4,5,6,7,8)
On the first try, I do not have a verbal reply until after the number 5 is decoded. Everytime after it works like a champ. Then randomly, the welcome menu message plays. Once it plays, I enter the password again, this time I have a verbal response everytime. Once all eight numbers are entered, the program should play the menu message, but it doesn't happen. I just press a few more numbers and then we start all over at the welcome message. I am boggled. I thought it may be the power supply, but I have caps on the pic, the op amp (lm 741), and the dtmf decoder. I know all the sound recordings work as I wrote a program to verify that. I know the decode sequence works as well as I have checked this out as well. It is this damn password and array that seems to be the problem. Thanks.
