Thanks XConnect for pointing out that post.
I should perhaps mention that I have also learned that the cable for connecting to the VS-VML is not a simple crossover. I had based that assumption on
https://www.sundance-communications.com/cgi-bin/ultimatebb.cgi?/ubb/get_topic/f/29/t/000064.html but apparently that does not apply to Adix-VS.
A developer at Zero Assumption Recovery (
https://www.z-a-recovery.com ) provided an astonishing level of support for their product and actually wrote a custom tool that allowed me to restore the flash card to the state it was in before I reformatted it. (I had created a "ZAR" image before working on the card.)
Unfortunately, even in its original state, the voicemail card is still not functioning and will not accept a connection from the VMI System Editor. That means it needs repair, and the prices we have been quoted for repair have led us to conclude that it's not worth repairing. Looks like we'll be replacing the system with a Linksys VoIP solution.
Thanks to those here who tried to help.
