Dave,

I used to do quite a bit of dial up with a 7855, and sometimes they will
stay up for days, and sometimes for just minutes.  Once the other side
is configured properly, the only issues I ever had were due to line
quality.  

Try putting a phone on the line and listen to the dial tone.  You might
find a bunch of static on the line indicating a bad pair, which has
happened to me two or three times.

Just in case, it looks like spares are quite cheap:
