Software to play MP3 to caller.

[garpttsr]

Hello all,

Forgive me if this has been posted elsewhere, i searched but didn't find anything. I was looking for a software that would play a predetermined MP3 to a caller either based on caller ID, or manual launch. I have need of playing a pre-recorded statement to particular people that call. I have them all grouped and cataloged. Darn press people. IS there such a software that exists, either pay or free (preferred) for this function? I know that the in-call recorder is out there, so something kind of the reverse.

Well, thanks again for any help you can offer.
