Configuring FortiVoice to send faxes

1. Go to Call Feature > Fax > Sending Rule and click New.
2. Enter a Name and click Enable.
3. Under Dialed Number Match, click New.
4. Enter a Match Pattern number. This is the extension number pattern in your dial plan that can match many different numbers for sending faxes.

The following pattern matching syntax is supported, in order to match a wide range of potential numbers:

Syntax	Description
X	Matches any single digit from 0 to 9.
Z	Matches any single digit from 1 to 9.
N	Matches any single digit from 2 to 9.
[15-7]	Matches a single character from the range of digits specified. In this case, the pattern matches a single 1, as well as any number in the range 5, 6, 7.
.	Wildcard match; matches one or more characters, no matter what they are.
!	Wildcard match; matches zero or more characters, no matter what they are.

5. Enter any required Modification settings, such as stripping or appending prefixes or postfixes to the number pattern, and click Create.
6. Under Call Handling, click New.
7. Set the appropriate Schedule, Action, and Outgoing trunk and/or Caller ID modification for your dial plan requirements, to determine the call handling action for the numbers matching the configured number pattern.
8. Click Create, and Create again to finish configuring the Sending Rule.

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. 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.

A T.38 fax requires significantly less bandwidth, and helps mitigate packet loss.

4. T.38 uses UDP Transport Layer (UDPTL) as its transport protocol. Enter the start and end ports.
5. 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.
6. Set a Retry interval and Wait time for an answer to the duration of time in seconds that the FortiVoice unit will wait between retries and the wait time for a "go-ahead" signal from the fax receiving terminal.
7. Click Apply.
