Creates a new conference directory for use in your organization. Conference directories are used to help dial-in conferencing users locate conference information. This cmdlet was introduced in Lync Server 2010.


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



Creates a new conference directory with the Identity 42. This directory will be hosted on the pool

Copy Code
New-CsConferenceDirectory -Identity 42 -HomePool ""

Detailed Description

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, Lync Server 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




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




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.




Prompts you for confirmation before executing the command.




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




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

Input Types

None. The New-CsConferenceDirectory cmdlet does not accept pipelined input.

Return Types

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