FortiVoice Cookbook

Configuring general fax settings

  1. Go to Call Feature > Fax > Setting.
  2. Enter a System station ID and System fax header that shows on each fax sent from the FortiVoice unit.
  3. You can adjust the Maximum Transmission Rate and Minimum Transmission Rate.
  4. The Enable T.30 ECM (error correction mode) is enabled by default. This mode can detect and correct errors in the fax page data to make the fax transmission successful.
  5. Under T.38 Fax, determine whether the FortiVoice unit will resend a T.38 invite if the remote end is unresponsive, and whether the FortiVoice will fallback to G.711 mode if T.38 communication fails.
  6. A T.38 fax requires significantly less bandwidth, and helps mitigate packet loss.

  7. T.38 uses UDP Transport Layer (UDPTL) as its transport protocol. Enter the start and end ports.
  8. Under Send Queue, set Max retry times to the maximum number of times the FortiVoice unit will attempt to resend a fax if the fax is unable to be sent due to busy lines.
  9. Set a Retry interval to the duration of time in seconds that the FortiVoice unit will wait between retries.
  10. Set a Wait time for an answer to the wait time for a "go-ahead" signal from the fax receiving terminal.
  11. Click Apply.
