Removes a voice normalization rule. Voice normalization rules are used to convert telephone dialing requirements (for example, dialing 9 to access an outside line) to the E.164 phone number format used by Microsoft Communications Server 2010.


Remove-CsVoiceNormalizationRule -Identity <XdsIdentity> [-Confirm [<SwitchParameter>]] [-Force <SwitchParameter>] [-WhatIf [<SwitchParameter>]]


Parameter Required Type Description




The unique identity of the rule to be removed. If the Identity specified includes the scope followed by a slash, and then followed by the name (for example: site:Redmond/Rule1, where site:Redmond is the scope and Rule1 is the name), the one rule with that unique Identity will be removed. If the value passed to the Identity contains only the scope (site:Redmond), all normalization rules at that scope will be removed.




Prompts you for confirmation before executing the command.




Suppresses any confirmation prompts that would otherwise be displayed before making changes.




Describes what would happen if you executed the command without actually executing the command.

Detailed Description

This cmdlet removes a named voice normalization rule. These rules are a required part of phone authorization and call routing. They define the requirements for converting (or translating) numbers from an internal Communications Server format to a standard (E.164) format. An understanding of regular expressions is helpful in order to define number patterns that will be translated.

Rules that are removed by using this cmdlet will be deleted from the dial plans of the organization, so they won’t be returned by the Get-CsVoiceNormalizationRule cmdlet and will not appear in the NormalizationRules property returned by a call to the Get-CsDialPlan cmdlet. This means that calling Remove-CsVoiceNormalization rule could leave a dial plan with no normalization rules.

Return Types

This cmdlet deletes an object of type Microsoft.Rtc.Management.WritableConfig.Policy.Voice.NormalizationRule.
