This video will walk you through configuring the DID Whitelist feature in RightFax.

Hello my name is Jay Campbell with The Fax Guys for RightFax University.

This video will walk you through configuring the DID Whitelist feature in RightFax.

This video was recorded at 1280 by 720 resolution for High Definition and is best viewed in full screen mode.

RightFax 10.0 SR3 and later can be configured for a DID (Direct Inward Dial) whitelist to prevent spam and unwanted faxes. This functionality only allows incoming faxes with DID numbers (extensions) in the whitelist. Faxes to invalid DID numbers are blocked. Without the whitelist feature, faxes to invalid DID numbers typically are routed to the Administrator mailbox.
Creating the DID Whitelist

A whitelist, which is a listing of the allowed DID numbers, must be created. Typically, it consists of all DID numbers used by RightFax, but this is not a requirement. Anything after a semicolon (";") is considered a comment.

Example:

Four DID numbers are in a whitelist: 1111, 1112, 1113, and 7777.

You can output a list of all RightFax DID numbers, using the administrative utility impuser.exe. For more information on impuser.exe, see the Administrative Utilities help file.

Example:

impuser -f<RightFaxServerName> -oc:output.txt -uAdministrator

Enabling the DID Whitelist

NOTE: Before proceeding, back up the Windows registry. For more information, see the Registry Editor help topics.

1.In Windows Registry Editor, open one of the following subkeys:

32 bit: HKLMSoftwareRightFaxDocTransportsTransportsBrooktrout
64 bit: HKLMSOFTWAREWow6432NodeRightFaxDocTransportTransportsBrooktrout

2.Create a new String value called DIDWhitelistFilename.

3.For this new value, enter the UNC path and file name of the text file.

4.Save the changes, and close Registry Editor.

5.Restart the DocTransport service.
Verifying the DID Whitelist Is Working

When a fax is rejected because the DID number is not on the whitelist, information is not logged in the Windows event logs. To verify the whitelist is working, change the DocTransport event log level to verbose.

Example:

A fax may be received with DID number 7776, but this number is not on the DID whitelist. With the DocTransport event log level set to verbose, the following appears:

CH[4] Brooktrout: Loaded 85341544 entries from DID Whitelist [7776]..
CH[93974224] Brooktrout: Skipped Receive. Routing code [ ] is not on the whitelist.

that's all for using the DID Whitelist feature in RightFax.
