Fax Automated Retries

When a fax you send fails to deliver, the fax will retry automatically before it is reported as a failure.

The flow is:

1. Fax sending is attempted, but fails
2. Fax transmission waits
3. Fax sending is attempted again, but fails
4. Fax is marked as a failure and the sender is notified

By default, faxes are retried 10 minutes after the first failure. There are two places this could be changed:

1. Your sending email address's configuration can be updated so faxes are reattempted on a different schedule (eg retried 3 times with 5 minutes in between)
2. Limited by the failure type (eg "Voice" failures are limited, whereas "Busy" failures are not limited

Failure types that limit the duration and frequency of retries:

• Bad Number
• Invalid Number Format
• Unallocated Number
• No Answer
• Voice
