Faxing over VoIP technology like CLEAR Voice can sometimes be a problem.

Here are some steps you can try that have worked well for many of our customers:

• Enter *99 before dialing the fax number on your fax machine. It can also a good idea to include a “pause” or comma after the *99. (Some fax machines will let you program this prefix to automatically dial.)

• Set the “Baud Rate” on your fax machine to 9600. If the machine does not have Manual Baud rate settings, it most likely makes Baud adjustments automatically.

• Turn ON the “International Mode” to allow the machine to negotiate the transmission speed automatically.

• Turn OFF “Error Correction Mode” on fax machine to improve the success rate when sending faxes .

• For machines that have both phone and fax capabilities, set the machine to “FAX ONLY”. This will enable your fax machine to automatically receive a fax. You will still be able to make and receive phone calls.

• Set the fax resolution to “Standard”

(For more information about these settings, please see your fax machine manual. )

More Troubleshooting Hints:

• The voicemail-waiting indicator can cause interference with faxes . You should pick up the phone and listen for the stutter dial tone. If you hear this tone, you should listen to your voicemail before sending a fax or processing the credit card.

• Outbound faxing to electronic fax services may not be compatible with CLEAR Voice.

• Because there are so many versions and variations, CLEAR cannot publish instructions or a list of supported devices. For additional help and troubleshooting, check your fax manual or contact the manufacturer.
