Errors

Voxtelesys provides error details, if applicable, to your callback URL via an error field. The error field provides a unique code identifying the error and is primarily intended to help you self-diagnose the issue.

Voxtelesys uses an error schema that is comprised of a 4 digit code. The first digit is used to determine if the error was caused by the client (customer) or server. The remaining 3 digits are error specific codes.

  • Client Errors (4xxx):
    • Voxtelesys Rejected, or
    • Carrier Rejected
  • Server Errors (5xxx):
    • Voxtelesys Rejected, or
    • Carrier Rejected

Client Errors​

A 4xxx error code indicates that Voxtelesys or the downstream carrier has identified some element of the email request to be unacceptable. Repeating the request will produce the same result. The exceptions are 4503 and 4504, which are temporary rejections by the recipient's mail server, so a later send may succeed.

Server Errors​

A 5xxx error code indicates that either Voxtelesys or the downstream carrier has reported a service failure. For Voxtelesys failures, the customer can retry the request and expect a different result. For downstream carrier errors, a retry may also yield a different result.
