Using the TestFAX diagnostic tool

If you have a problem sending or receiving faxes with a Diva SDK-based, or CAPI 2.0-based, fax application, try testing with the Diva Utility Testfax to determine if the problem is located within the application or with the Diva Media Board itself.

• Test outgoing faxes
• Test Incoming faxes

Where to find Testfax

Testfax.exe is normally provided with the System Release for the Diva Media Boards. 

How to use Testfax to test outgoing faxes:

• Create a file with Notepad, for example, and type in some text. 
• Save the file in the same folder where Testfax.exe is located on your PC.
• Open a Command (DOS) prompt and type:

testfax filename <Number>

- where <Number> is the number of the fax machine that you want to send the file to and "filename" is the name of the text file you have just created.

For example:

testfax myfile.txt 0208123456

Note: When sending a fax using a Diva 4BRI (or if you have multiple Media Boards installed), it is necessary in addition to specify the controller. For example:

testfax /c1 filename <Number>

(where 'c1' is controller 1 on the 4BRI card)

• Typing testfax/? will display the various parameters that can be used.

For example, to send a fax that displays the originating number to the recipient, type:

testfax filename <Number> /o30

- and replace '30' with the MSN number on the line that you want displayed as the originating number

How to use Testfax to test incoming faxes:

• Open a Command (DOS) prompt and move to the directory where the Testfax software resides
• Set up the server as a Testfax server by typing:

Testfax /serve

To receive a fax on a specific controller on a 4BRI card (or on a specific card if you have multiple Media Boards installed):

Testfax /serve /c1

• Successful receipt of a fax is indicated by creation of a file called RCV.SFF in the same folder where Testfax.exe is located.

Note: If you receive more than one fax, the RCV.SFF file will be overwritten. Therefore, to confirm that a fax IS received, ensure that you delete the RCV.SFF after you receive each fax.
