It should be technically feasible.

Modern modems are not modems anymore; they are just sound cards
attached to telephone jacks, so if you want to exchange data with
another modem you need a softmodem driver which is a DSP-like software
mathematically creating the correct sound waveform to play into
the line.

With this kind of hardware, sending audio captured by a mic to
the they-call-me-modem-but-i-m-a-soundcard component should be
quite easy to do.
But I don't know if such a software exists.
