I am splicing audio files together for a phone tree. I am saving in CCiTT U-Law, 8bit, mono and each file that i save ends with .12sec of static at the end.

How do I eliminate this?

This can sometimes get tricky with u-laws in Sound Forge. The first thing to try is to go to Options-->Preferences-->General and make sure the, "Ignore fact chunk when opening compressed Wave files" box is UNCHECKED.

Try a very short fade-to-zero at the end of each section. Ending a file at a high instantaneous value will do all sorts of things to different replay devices.

Geoff, this probably won't work, since the static is typically misinterpreted header information, and not actually audio. It will seem to reappear after every save.

This is exactly the problem I was having with ADPCM files. This solved the problem and fixed the timing issue as well. Thanks.
