Follow the steps below if you want to create or modify a normalization rule manually. Alternatively, if you want to create or modify a normalization rule by using the Build a Normalization Rule tool, see Create or Modify a Normalization Rule by Using the Build a Normalization Rule Tool for the procedure.

Important:
To define a normalization rule, follow the procedure to create or edit a dial plan and create or edit a normalization rule as explained in those procedures. For more information, see Create a Dial Plan or Modify a Dial Plan.

To define a normalization rule manually

  1. In the New Normalization Rule or Edit Normalization Rule dialog box, type a name in the Name field that describes the number pattern being normalized. For example, name the normalization rule 5DigitExtension.

  2. (Optional) In Description field, type a description of the normalization rule (for example, "Translates 5-digit extensions").

  3. Click Edit at the bottom of the Build a Normalization Rule tool.

  4. Enter the following in the Type a Regular Expression dialog box:

    • In the Match this pattern field, specify the pattern that will be used to match the dialed phone number.

    • In the Translation rule field, specify a pattern for the format of translated E.164 phone numbers.

    For example, if you enter ^(\d{7})$ in the Match this pattern field and +1425$1 in the Translation rule field, the rule will normalize 5550100 to +14255550100.

  5. (Optional) If the normalization rule results in a phone number that is internal to the enterprise, select Internal extension.

  6. (Optional) Enter a number to test the normalization rule and then click Go. The test results are displayed below the Enter a number to test field.

    Note:
    You can save a normalization rule that does not yet pass the test and then reconfigure it later. For more information, see Test Voice Routing.

  7. Click OK to save the normalization rule.

  8. Click OK to save the dial plan.

Any time you create or modify a normalization rule, you must run the Commit All command to publish the configuration change. For more information, see Publish Pending Changes to the Voice Routing Configuration.
