I'm not sure I understand your question.  If you could phrase it more plainly,
I would have more confidence in answering it.

I think you want to know if it can cause any trouble to call an answering modem
with a voice telephone call instead of another modem?  If that is what you are
actually asking, then the answer is that it is perfectly safe.  If you are
using any reasonable software such as mgetty to answer the modem, then it
should always recover into a perfectly stable and well defined state.
