RightFax – Blocking Outbound Fax Numbers with Dialing Rules and Destination Tables

Blocking Outbound Fax Numbers in RightFax Using Destination Tables

Overview
RightFax supports creating outbound dialing restrictions using Destination Tables combined with Dialing Rules. This allows administrators to block specific numbers, ranges, or lists of numbers from being dialed, ensuring compliance and reducing misdials.

Steps to Configure

1. Create a Destination Table

  1. Open Enterprise Fax Manager (EFM) and authenticate.

  2. Navigate to Dialing Plan → Destination Tables.

  3. Insert a new table (Right-click → New or press Insert).

  4. Give the table a short, descriptive name (e.g., Blocked).

  5. Add entries:

    • Insert Range: Add sequential ranges of numbers (digits only).

    • Insert Text: Paste or type specific numbers (digits only, no dashes/spaces).

  6. Click OK to save.

2. Create a Dialing Rule

  1. Go to Dialing Plan → Dialing Rules.

  2. Insert a new rule (Right-click → New or press Insert).

  3. On the Matching tab, configure the Pattern field:

    %[Blocked,10]+

    • Blocked = name of the Destination Table.

    • 10 = the first 10 digits of the dialed number to check against the table.

    • + = allows additional digits beyond the matched 10.

    ✅ Example:

    • Table entry: 5035551114

    • Dialed number: 5035551114 → Blocked.

    • Dialed number: 9105551131 → Allowed (not in table).

  4. Under Priorities, select which faxes this rule applies to (usually all).

  5. On the Other tab:

    • Choose Disallow Sending.

    • Add a comment (e.g., Block outbound numbers).

  6. Save the rule (use CTRL+S if required).

3. Test the Rule

  1. In EFM, go to Dialing Plan.

  2. Enter a test number in the Phone Number field.

  3. Click Rule Execution:

    • If the number is blocked, you’ll see: “Rule disallowed by the dialing plan.”

  4. For more detail, click Route Trace:

    • This shows step-by-step execution, confirming whether the number is blocked or allowed.

Key Notes

  • Numbers in Destination Tables must be digits only (no formatting).

  • Multiple rules can be created for different classes of traffic (production, non-production, SMS).

  • Always validate new rules with Rule Execution and Route Trace before deploying.
