Per a suggestion, I swapped out the offending unit with a brand-new unit
that came running 2.0.13(GWa) firmware.  It's worked fine for the few test
calls I just made.  Will leave that in place for a couple days and see.

If it stays working, I'll want to downgrade the firmware in the original
unit.  Is it safe to downgrade them?

Thanks for all the suggestions,

Paul
