On my Dell Inspiron 8600, lshw says:

Even though I don't use the modem for data connections, I use it as an
answering machine with vgetty/mgetty. I too had problems of reliability
and predictability.

Your problem might be different, but I solved my reliability problems
with this script:
# This script takes care of reloading the modem driver in the proper
# order
# This is necessary because the snd-intel8x0m gets loaded first and the
# slamr driver then is not. The modprobe slamr removes the
# snd-intel8x0m
# driver
/etc/init.d/sl-modem-daemon stop
sleep 1
modprobe -v slamr
sleep 1
/etc/init.d/sl-modem-daemon start
sleep 1
telinit q
That is called from /etc/rc.local
