TCL VoiceProHow Fax Calls Are Routed
If you have a fax machine, you can connect it to one of the extension jacks on the VoicePro.
Then enable Fax Detection and incoming fax calls will automatically be routed to that
extension where you have your fax machine connected.
To enable Fax Detection with the VoicePro you need to do the following...
- Use function 31 to specify which CO lines may receive incoming fax calls. This causes a slight delay when answering, in order to wait for a CNG signal that is sent by the sending fax machine.
- Use function 7 to specify the extension where you connected your fax machine.
If no fax CNG signal is detected, or if the caller makes a regular voice call, then the Automated Attendant will answer the call. In that case the caller can manually dial any extension or select any menu option you programmed into the VoicePro.
How Fax Detection Works
The originating fax machine sends a CNG signal (1100 Hz) to indicate that this is a fax call. The VoicePro 'listens' for that signal before the auto attendant answers. If it does not hear that signal it handles the call as a regular voice call. If it hears the CNG signal then it immediately passes the call to your fax machine. Your fax machine will then detect the repeating CNG signal and 'handshake' by responding with a CED tone (2100 Hz) to indicate that it's ready to receive the transmission.Some people make the mistake of initiating a fax call by dialing the fax number with the fax machine's handset off hook. The VoicePro will incorrectly detect this as a voice call. The sender needs to press the "Send Fax" button on their machine, or simply dial without using the handset, in order for the VoicePro to properly know this is an incoming fax.
ALTERNATIVE FAX IDEA:
If you would rather receive your faxes in your e-mail as a PDF file,
I recommend Kall8...
It gives you a dedicated fax line for only $2 per month and less than 7¢ per fax page.
That's a lot cheaper than another phone line for your fax.
I use it for our office fax. It saves paper too since I get the faxes via email.
Kall8 service includes a toll-free number and you can select one from a list for instant activation. Then you can use your wired fax line as an extra voice line to handle more callers. Or get ride of it entirely and save the money with a $2 toll-free dedicated fax line from Kall8.
