While trying to track down this problem, I started checking my
modems, one at a time, by typing 'sho mX'. All looked ok, no errors
at all, except for one. Here's the result of 'sho m5':

This pm3 was just rebooted yesterday afternoon - it shows it received
41 calls, 36 which were considered good. Now why would it show
millions of failures? And if this is the 'broken' one, I think its
strange that it shows an active call! At this point, I think I have
an issue with the PM3 modem, so I'll open a ticket with support, just
thought I would share this with the list.
