Anyone experience issue with Fax in sandbox account

We are trying to send out fax and receive fax in our sandbox account. But have no luck.

I notice the "To" values are always overwritten to the below regardless of what we put in.

  "to": [
    {
      "recipientId": "8322067004",
      "phoneNumber": "+625328625328",
      "messageStatus": "SendingFailed",
      "faxErrorCode": "ProhibitedDestination"
    }
fax

Can you clarify this "I notice the "To" values are always overwritten to the below regardless of what we put in." Was the recipient number an international phone number?

Hi Phong,
So essentially, we put in a USA fax phone number from RingCentral (our sandbox fax number: +18582470309) but when I check the payload, the to number is to an international number, and it just fail saying destination not found.

Just to confirm. So you cannot send a test fax from your production account to your sandbox main company number (+18582470309), right? I check your account log and see a few in and out faxes received and sent successfully.
