I wouldn't be surprised if the line doesn't drop now & then even at 9600 -
there's enough weirdness going on in the B.A. network that this is pretty
much routine.  I've been able to keep 28.8 links up for 4-5 days, but I've
also seen periods (like after a rainy day) when they've dropped every few
hours.  If your software can just re-dial, this isn't too serious - you'll
be down for 30 seconds at a time while the modems reconnect, but usually
this isn't a big problem.  

If you want solid reliability, consider a dedicated ISDN link.  B.A. will
give you a flat-rate deal based on mileage.  ISDN is a lot more solid to
start with, and if the link does go down, it'll come back up in about 0.8
second so you probably won't even notice.  You also get a lot more
bandwidth.  Of course, this isn't in the same cost category as a couple of
modems and a POTS line ...
