[VoiceOps] Problems with defective Adtran TA900s

I just swapped out a 916 that had a bad flash.  Adtran support sent an
advanced replacement in a few days.  I've used the TA900s and found Adtran's
support was much better(free).  It's almost impossible to get any real help
on the Cisco boxes without a Smartnet contract.

Have had a small rash of flash chip failures but beyond that with 
hundreds in the field I can count the number of DSP failures on one hand.
