Creates a new conference directory for use in your organization. Conference directories are used to help dial-in conferencing users locate conference information.

New-CsConferenceDirectory -Identity <XdsGlobalRelativeIdentity> -HomePool <String> [-Confirm [<SwitchParameter>]] [-Force <SwitchParameter>] [-WhatIf [<SwitchParameter>]]

When you create a dial-in conferencing Uniform Resource Identifier (URI), those URIs are assigned unique SIP addresses. However, SIP addresses are difficult to translate to devices that are not SIP-aware; for example, a public switched telephone network (PSTN) telephone can’t translate a SIP address. Because of that, Microsoft Lync Server 2010 uses conference directories as a way to help these devices locate, and connect to, dial-in conferences. This is done by creating a SIP conference directory that is associated with each dial-in conferencing URI, and is identified by an integer value rather than a SIP URI. PSTN telephones and other devices can then use these numbers (rather than a SIP URI) when connecting to conferences; the directory number is included in the PSTN conference identification users enter when connecting to a dial-in conference.

New conference directories can be created by calling the New-CsConferenceDirectory cmdlet.

Who can run this cmdlet: By default, members of the following groups are authorized to run the New-CsConferenceDirectory cmdlet locally: RTCUniversalServerAdmins. To return a list of all the role-based access control (RBAC) roles this cmdlet has been assigned to (including any custom RBAC roles you have created yourself), run the following command from the Windows PowerShell prompt:

Get-CsAdminRole | Where-Object {$_.Cmdlets –match "New-CsConferenceDirectory"}


Parameter Required Type Description




Unique numeric identifier for the new conference directory. Identities can be any integer value between 0 and 9999 inclusive; however, Identities must be unique. (For example, you cannot have two directories with the Identity 575.) You do not need to follow a numeric order when creating new directories. For example, you can create a directory with the Identity 999 followed by a directory with the Identity 2 followed by a directory with the Identity 438, and so on.




Fully qualified domain name (FQDN) of the Registrar pool where the new conference directory will be hosted. For example: -Identity



Switch Parameter

Suppresses the display of any non-fatal error message that might occur when running the command.



Switch Parameter

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



Switch Parameter

Prompts you for confirmation before executing the command.

None. New-CsConferenceDirectory does not accept pipelined input.

Creates new instances of the Microsoft.Rtc.Management.WritableConfig.Settings.PstnConf.ConferenceDirectories object.
