Fax Failure Notifications
When you send a vFax, the system may attempt delivery up to 3 times. This means you could receive as many as 3 failure notifications for the same fax.

  • If you receive a “Fax Sent Successfully” or “Fax Queue Confirmation” email, your fax has gone through — no action is needed.

  • If you receive 3 consecutive failure notifications and no success confirmation, please forward the 3rd failure email to support@soundcurve.com.

Otherwise, review the common reasons for fax failures below and follow the troubleshooting steps.


1. Incorrect Fax Number Format

  • Make sure you are dialing the fax number exactly as required:

    • Confirm you addressing your email correctly: fax[destinationnumber]@titaniumvfax.com

    • Do not include a leading 1 in the destination number.

    • Email must be sent in Plain text format.

    • You may attach ONE document for faxing at a time. The following file types are supported: .pdf, .doc, .docx, .xls, .xlsx, .rtf, .ppt, .pptx, .tiff


2. Busy or Offline Receiving Fax Machine

  • The destination fax machine may be busy, offline, or out of paper.

  • Try resending the fax after a few minutes.

  • Try calling the fax number you are attempting to fax and confirm it is an active number, and you hear fax tones.


3. File Format or Size Issues

  • Ensure the document is in an accepted file format (PDF, TIFF, or DOC are most common).

  • Large files may fail. The size of the attachment is only limited by your email server.


4. Network or Service Interruption

  • Temporary internet or carrier issues can interrupt fax transmission.

  • If you continue to see repeated failures, open a support ticket.
