This is DTMF Dial V1, a user mode program that should run on many PSP firmware variations.
DTMF Dial is a 25 entry phone book, editor, and auto dialer.
Full instructions are included in the readme file.
DTMF samples are 44100hz (CD quality),
but I probably do need to fiddle with the length of pauses for the next version.
