But basic voice calling should be possible with this modem itself.
Most modern modems (by "modern" I mean compared to the 2400bps Microteks we used to use back in the early 1990s) have audio handling through AT commands. Hypothetically it should be possible to write a program that captures audio from the modem, transcodes it and plays it through ALSA, as well as the reverse: capture ALSA audio, transcode it and play it back to the remote party through the modem.
It will require some programming, though, unless it has already been done by some kind soul on the 'net.
