How to use voice modem as hands-free phone.

I have an external 33600 SupraExpress voice-fax modem attached to my
Linux box, and I would like to use it as hands-free set. The modem has
a microphone input and an "audio" output, it seemed so easy that I
decided to try out. I dial with kermit and I'm able to listen to the
dialing tones, also the the voice of guy who I'm phoning but it seems
that the microphone part is not working. Does anyone figure out why ?
Is there any software able to set the modem in voice mode (if this is
the problem) and dial or vice-versa ? Kermit does the job but is far
from comfortable.
Thanks,
Toni.

A modem needs to be sent a special command to switch it into "Speakerphone
Mode" - which "turns on" the mic and external speaker.

Yes. Try the vgetty package. With vgetty, in addition to data you can use
the modem for voice and Class 2 fax. The modem can be set up as an
answering machine for voice/data/fax and/or used maunally as a
speakerphone.
