Fax Send with invalid number
Scenario: Testing invalid fax number response codes by faxing to the number 5
Expected: 400 status code with message telling me what field is bad and maybe a FaxResult type telling me InvalidOrMissingNumber (or 8)
Actual: Receive 500 response with no detail, occasionally a 400 status code is returned but with no detail describing what went wrong.
There is inconsistency between the Http Status Code returned, and would be nice for some details regarding what went wrong.
