Adtran Total Access 900 Series failed DSP

One of my Adtran Total Access 904 units stopped passing voice traffic and started producing the following errors:
2012.01.10 14:22:18 SB.CALL 8 RTP resource unavailable or SDP negotiation failed. Call from (XXXXXXX) to (YYYYYYYY).

A “show version” revealed the problem. It is supposed to show information about the DSP but it did not.

A normal operating unit will show something similar to the following:

slot 0, DSP 1
DSP software version: G1.A4.00.31
DSP hardware version: Freescale MSC7116
Total channels: 24

If it does not it means that the DSP failed and the unit needs to be returned to Adtran for repair.
