Retrieves one or more trunk configurations, which describe the settings for a trunking peer entity such as a public switched telephone network (PSTN) gateway, IP-private branch exchange (PBX), or Session Border Controller (SBC) at the service provider.

Get-CsTrunkConfiguration [-Identity <XdsIdentity>] [-LocalStore <SwitchParameter>]
Get-CsTrunkConfiguration [-Filter <String>] [-LocalStore <SwitchParameter>]

Use this cmdlet to retrieve one or more trunking configurations applicable to PSTN gateway entities. Each configuration contains specific settings for a trunking peer entity such as a PSTN gateway, IP-PBX, or SBC at the service provider. These settings configure such things as whether media bypass is enabled on this trunk, whether real-time transport control protocol (RTCP) packets are sent under certain conditions, and whether to require secure real-time protocol (SRTP) encryption.

Who can run this cmdlet: By default, members of the following groups are authorized to run the Get-CsTrunkConfiguration cmdlet locally: RTCUniversalUserAdmins, 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 "Get-CsTrunkConfiguration"}


Parameter Required Type Description




The unique identifier of the trunk configuration you want to retrieve. Trunk configurations can be defined at the Global scope, the Site scope, or at the Service scope for a PSTN Gateway service. For example, site:Redmond (for site) or (for service).




This parameter accepts a wildcard string and returns all trunk configurations with identities matching that string. For example, a Filter value of site:* will return all trunk configurations defined at the site level.




Retrieves the trunk configuration from the local replica of the Central Management store, rather than the Central Management store itself.

This cmdlet returns an object of type Microsoft.Rtc.Management.WritableConfig.Settings.TrunkConfiguration.TrunkConfiguration.

-------------------------- Example 1 ------------------------


This example retrieves all trunk configurations for the Microsoft Lync Server 2010 deployment.

-------------------------- Example 2 ------------------------

Get-CsTrunkConfiguration -Identity site:Redmond

This example retrieves the trunk configuration with the Identity site:Redmond. Because identities are unique, this command will return at most one object.

-------------------------- Example 3 ------------------------

Get-CsTrunkConfiguration -Filter site:*

Example 3 retrieves all trunk configurations defined at the site level. The Get-CsTrunkConfiguration cmdlet uses the Filter parameter to retrieve all trunk configurations with an Identity beginning with site:, meaning all trunk configurations defined at the site level.
