When troubleshooting has failed to provide a solution to your problem, it's time to contact our support team. We'll need the following information:
  1. Your public IP address at the time you were testing (when in doubt, google "what is my ip" to get this)
  2. One ore more specific call records for us to research. A call record is the exact date & time (including timezone) and the phone number of both caller and recipient, if available
  3. Any diagnostic error messages being displayed by your T.38 software
  4. A plain english description of your problem (for instance, I am trying to receive faxes to my Power-T.38 phone number(s) but it is always busy)
Our support ninjas often need wireshark packet captures from your side, so collecting one of these is never a bad idea. Submit your case online using our support form. Support is currently provided in English.
