AFAIK, gsm is lossy, which is why it doesn't sound good.
wav, however, should sound great. What codec are your calls in? Are you
recording many calls?
Check the load average while you are recording. If it's greater than the
number of CPUs then probably your hard drives can't keep up. There are
several options then, first let see if we can diagnose the issue.
