Try setting the ATS7 register a little higher on the modem.  It's the one that
tells the modem how long a carrier loss should be before it will disconnect.
When the call-waiting signal comes in and the ATS7 is set high enough, the
modem will just wait out the amount of time specified and hopefully by then
the carrier will be back.  You'll get some garbage on both ends of the line
but it's better than being disconnected.
