You wrote this here, but elsewhere what you wrote seems to suggest the symptoms seem more "random" than this (sometimes all digits are correctly decoded and passed on, sometimes different digits or different numbers of digits are missing, etc.).

If the mode of failure really is as consistent as you suggest here, though (or even if it happens the majority of time), have you considered recording the audio coming out of one of the fire alarm panels while it's trying to dial, so that you can take a spare Adtran, put it on the bench, configure it identically to one that you have in the field, and feed it a recording of the fire alarm panel dialing out, in order to reproduce the issue?  If you can repro outside of production, then you can test & iterate much more quickly (as well as at your own convenience) than when you are forced to test on an actual customer installation.
