I have the same problem on 3.0-RELEASE. It doesn't happen very often
but it's a pain when it does. I kill the ppp process and unplug the
modem->phone cable for a minute or so. After re-starting ppp all's
well. I've no idea what causes it, neither have I a cure for it.
It's just one of those things I guess.
