Experts Please help

Hi Guys,

I am trying to develop an application which will connect to the telephone line and when I get an incoming line it shall send a voice data on the phone line and then look for key entries from the other side ... similar to a voice mail system. I have figured out that I would need a DAA to interface to the phone line (of course a one that would have a DTMF decoder so that I can get the key entries). Now my question is how do I send the voice data out (this voice will be pre-recorded on a flash). All the places I have looked say that I would need PCM data interfaced to a DSP.

I do not want to complicate the matter -- I want to make it simple by using a PIC Microcontroller.

So basically this is what I plan it would look like:

RJ11 DAA Serial Interface PIC Micro Flash

This should take care of both voice and key entries.

I have looked into tons of options but cannot figure out a "simple" way to do this
