I found that I need to unload and reload the wcfxs module from the kernel and
re-run ztcfg.  Perhaps the former is no necessary, but it's in my script now.

I have been having trouble with E/Fs (the H seems to be more stable), but it's
not just with the first module.  In my case it is the second one.  And I
initially had trouble because the FXO was on socket 1.  Digium had me move it
to socket 4 and that helped some.  But only for a time.
