Multitech Analog Fax Finder

The Multitech Analog Fax Finder will require an FXS Gateway to register as an extension on the PBX. Once configured, the fax finder will be connected to the FXS Gateway to receive and send calls. Inbound calls define their recipient by sending DP Digits inband when the Fax Finder answers the call.

  • Register your FXS Gateway (Grandstream, PAP2, or IPr20) as an extension to the PBX.
    • Ensure that the DTMF modes in the PBX and the FXS Gateway match
  • Navigate to Call Routing=>Incoming
  • Point the desired Fax DID to the extension created for the Fax Finder
  • Click the box with ... to set DP Digits
    • The DP Digits should correspond to the User that was created in the Fax Finder. This way, when the Fax Finder answers, the PBX plays the digits into the line and the Fax Finder can email the fax to the correct recipient.

Under Inbound Routing, set up a Recipient account for each FAX extension created. All that is needed in the recipient information is the Name and Extension Number and to define a User. To define the user you must create a Fax User account, under Users - Multitech SIP Fax Finder IP Users.

Once this is configured, you can set a DID to a Fax extension. And test Inbound to this extension. The Multitech SIP Fax Finder IP will receive the Fax and email to the respective email address. For outbound you will need to install the Fax Finder client software. This is were you will need to configure the User and Password for outbound use. Once installed this is used as a Printer on your PC. And you simply print to the Fax Driver. It will send using the credentials provided.

In order for outbound faxing to work, a Custom Route must be built. The info that goes in will look like the text below, where trunk_8 must match the ID of the provider built for the fax finder. You can tell what trunk it is if you edit the provider and look in the address bar of your web browser.

[trunk_8](+) include => phone_XXXX

You must be running system software 4.8.0 and have Custom Routes enabled in your license for this to work
