Hi, I am trying to fax to Thailand, but it says "Failed - Prohibited destination". What causes the error and how do I fix it? Maybe there is an international fax feature or billing I have to turn on? Thanks.





There is indeed a setting.

I sent a fax last week to a 855 number successfully and today tried to do the same thing with the same number and the error I got was that international numbers were not permitted. I about pulled my hair out.  So, after 45 looooong minutes, I sent it with a 1 in front (1855xxxxxxx) and it finally sent it. I can't tell you how frustrating this was. I'm so disappointed.
