Not all faxes are wanted, which is why it’s necessary for some RightFax users to block spam faxes and unwanted messages from unfamiliar numbers. While the most effective way to block spam messages is to stop them before they even reach the fax server, this must be done at telephony or network level, which requires some knowledge of IT systems. Not everyone has the capability to do this.
RightFax users who just want a quick and effective fix can put a stop to spam faxes filling their users’ inboxes by implementing this best practice.
Routing Spam Faxes to a Designated RightFax User
This process in RightFax involves creating a new user account that will act as a designated account to receive spam from numbers who are frequently sending you unwanted messages. All you will need to accomplish this is the Automatic Number Identification (ANI) or Dialed Number Identification Service (DNIS) of the number in question.
Follow These Steps:
- In RightFax Enterprise Fax Manager, create a new user (we recommend naming it “SPAM” so that it’s obvious what the user account is used for).
- Create a Windows registry subkey ANI* that contains the Entries for every number you wish to block, these numbers will automatically be routed to the SPAM user account you have created.
*The Entries value is part of the Registry subkey ANI located at:
If the subkey does not exist, you will need to create it. The type will be REG_MULTI_SZ and the default will be left blank.
- In Registry Editor, find the subkey you have created and double click on it. This will bring up the “Edit Multi-String” window. Enter the ANI or DNIS numbers into the section labeled “Value data:”. You can add as many numbers as you want here.
- Click “OK” to finish the process. All faxes from those ANI or DNIS numbers will automatically be routed to your spam account.
