Once signed up, how do I make outbound T.38 fax calls?
All outbound T.38 fax calls need to be sent to us as using a prefix of *323 and then either a 10-digit or 11-digit number. So if we For example, if you wanted to send a fax to 9209991234 we someone at 5555551234, you would send the call to SIPStation as *3239209991234. The easiest way to do this is to setup a outbound route in FreePBX called Fax. Then add a simple prefix such as 9. So your users would dial 99209991234. We would then have the outbound route strip off the 9 and add the *323 for us as seen in the screenshot below.
Dont forget to drag the Fax outbound route toward the top fo your route list.
If using Fax Pro in 3235555551234.
If we do not receive *323 at the beginning of your number, outbound faxing will not work. In FreePBX, you will need to configure an outbound route accordingly. Unless users are faxing from the User Control Panel with a global fax prefix set up, they will need to dial *323 or a special prefix you have set up for faxing.
Configuring an Outbound Route for Fax
You will need to set up an outbound route that uses dial patterns involving *323 plus a 10- or 11-digit number. There are generally two ways you could set this up.
Example 1: The first option is to create dial patterns where a user must dial *323 followed by a 10- or 11- digit number. The advantage is that this somewhat simplifies things; the disadvantage is that users now need to remember to dial *323 before a fax number, and that may be difficult to remember.
Example 2: The second option would be to set up a special "simplified" prefix for users to dial. For example, you could allow your users to dial 9 plus any 10- or 11-digit number to send a fax as shown below. Your dial patterns would strip the 9 and prepend *323 to the beginning of the number. Users would not have to dial *323. (You can choose any prefix you would like. If you choose something like "9," the advantage is that users can more easily remember a single-digit number than the actual fax prefix of *323.)
Outbound Route Order
Don't forget to drag your Fax outbound route toward the top of your route list. It should be below any Emergency routes but above other types.
Global Fax Prefix
If using Fax Pro in FreePBX to send outbound faxes from the User Control Panel (ARIUCP) you , UCP can have it automatically set the 9 prefix for you so users facing from the User Control panel wont need to add the 9 when dialing. You do this in the Fax Configuration module in FreePBX
automatically add a fax prefix. The advantage of this is that UCP users would not have to remember any prefix when faxing from UCP. Instead they would just need to dial a 10- or 11-digit number. UCP would add the global prefix to the beginning of whatever the user dials. When setting this up, you just need to keep in mind that the resulting combination needs to match something in an outbound route for fax. Also keep in mind we need to receive *323 at the beginning of a 10- or 11- digit number in order for outbound faxing to work in SIPStation.
To set this up in FreePBX, go to Settings → Fax Configuration and look for "User Control Panel Faxing Options."
The global prefix you need to use will depend on what you've set up in your outbound route dial patterns. There are generally two ways you could set this up.
Example 1: If your dial patterns are *323NXXNXXXXXX and *3231NXXNXXXXXX (no prefixes or prepends), then your global prefix needs to be *323.
Example 2: If you have set up a "simplified" fax prefix as described earlier, then your global prefix needs to be whatever special prefix you have set up in the outbound route For example, if you want users to dial 9 when faxing, and you've set up a dial pattern that strips the 9 and prepends *323, then your global prefix would need to be 9.
Remember, if you set up a global prefix, users should not dial any prefix when faxing from UCP. They simply need to enter the fax number.
Enabling T.38 in Asterisk
Please note, in order to use SIPStation faxing, you must have Asterisk set up to handle T.38 at the Asterisk level. We are not able to offer technical support for this. FreePBX does have an option to enable T.38 in the Asterisk SIP Settings module, but you also need to make sure Asterisk is compiled for T.38.
In FreePBX, go to Settings → Asterisk SIP Settings → Chan SIP (right-hand side). Scroll down to Audio Codecs and make sure T38 Pass-Through is enabled.
