This you can not do with AT commands. If I you have a voice modem,
connect it to your sound card. But it's also a mess, becouse a modem
voice modem has mic. input, not signal input... your soundcard will
overdrive the modem.

A couple of resistors should fix that.

Hm-m... Sure one _do_ can use a voice modem for voice playback
without any sound cards. However, there is no AT command that
directly takes a filename as it's argument. Instead one shound
use an appropriate command to put the modem into Voice Transmit Mode
and then just read from file and send voice data to modem.

2OP: Consult your modem's manual for details.
