Kind of tough guessing at this without the config files that go with
it. Just a pure guess based on the modifyied debug stuff...
      -- Call accepted by 66.225.202.72 (format ULAW)
      -- Format for call is ULAW
      -- Hungup 'IAX2/NuFone/7'
implies NuFone isn't accepting ULAW across and IAX link, or the number
you are sending to NuFone is not valid.
