Test-CsDialInConferencing checks to see if a user can take part in a dial-in conferencing session.


Test-CsDialInConferencing -TargetFqdn <String> [-Force <SwitchParameter>] [-OutVerboseVariable <String>] [-RegistrarPort <Nullable>] [-UserSipAddress <String>]
Test-CsDialInConferencing [-TargetFqdn <String>] -UserCredential <PSCredential> -UserSipAddress <String> [-Force <SwitchParameter>] [-OutVerboseVariable <String>] [-RegistrarPort <Nullable>]


Parameter Required Type Description




Fully qualified domain name (FQDN) of the pool to be tested.



PS credential object

User credential object for the user account to be tested. The value passed to UserCredential should be an object reference obtained by using the Get-Credential cmdlet. For example, this code returns a credentials object for the user litwareinc\kenmyer and stores that object in a variable named $x:

$x = Get-Credential "litwareinc\kenmyer"

You need to supply the user password when running this command. This parameter is not required if you are conducting the test using the health monitoring configuration settings.



SIP address

SIP address for user account to be tested. For example: -UserSipAddress "". The UserSipAddress parameter must reference the same user account as UserCredential. This parameter is not required if you are conducting the test using the health monitoring configuration settings.




SIP port used by the Registrar service. This parameter is not required if the Registrar uses the default port 5061.



Switch Parameter

Reports detailed activity to the screen as the cmdlet runs.



Switch Parameter

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

Detailed Description

Test-CsDialInConferencing is an example of a Microsoft Lync Server 2010 "synthetic transaction." Synthetic transactions are used in Lync Server 2010 to verify that users are able to successfully complete common tasks such as logging on to the system, exchanging instant messages, or making calls to a phone located on the public switched telephone network (PSTN). These tests can be conducted manually by an administrator, or they can be automatically run by an application such as Microsoft System Center Operations Manager (formerly Microsoft Operations Manager).

Synthetic transactions are typically conducted in two different ways. Many administrators will use the CsHealthMonitoringConfiguration cmdlets to set up test users for each of their Registrar pools. These test users are a pair of users who have been preconfigured for use with synthetic transactions. (Typically these are test accounts and not accounts that belong to actual users.) With test users configured for a pool, administrators can simply run a synthetic transaction against that pool without having to specify the identities of (and supply the credentials for) the user accounts involved in the test.

Alternatively, administrators can run a synthetic transaction using actual user accounts. For example, if two users are unable to exchange instant messages, an administrator could run a synthetic transaction using the two user accounts in question (as opposed to a pair of test accounts) and try to diagnose and resolve the problem. If you decide to conduct a synthetic transaction using actual user accounts, you will need to supply the logon names and passwords for each user.

The Test-CsDialInConferencing works by attempting to log a test user onto the system. (If you are using test users, Test-CsDialInConferencing will use the first test account configured for that pool.) If logon succeeds, the cmdlet will then use the user’s credentials and permissions to try the available dial-in conferencing access numbers. The success or failure of each dial-in attempt will be noted, then the test user will be logged off from Lync Server.

Test-CsDialInConferencing only verifies that the appropriate connections can be made. The cmdlet does not actually make any phone calls or create any dial-in conferences that other users can join.

Who can run this cmdlet: By default, members of the following groups are authorized to run the Test-CsDialInConferencing 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 "Test-CsDialInConferencing"}

Input Types

None. Test-CsDialInConferencing does not accept pipelined input.

Return Types

Test-CsDialInConferencing returns an instance of the Microsoft.Rtc.SyntheticTransactions.TaskOutput object.


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

Copy Code
Test-CsDialInConferencing -TargetFqdn 

The preceding example verifies that a preconfigured test user can take part in dial-in conferencing on the pool This command will work only if test users have been defined for the pool If they have, then the command will determine whether or not the first test user is able to log on to Lync Server.

If test users have not been defined, then the command will fail because it will not know which user to log on as. If you have not defined a test users for a pool, then you must include the UserCredential parameter and the credentials of the user that the command should employ when trying to log on.

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

Copy Code
$cred1 = Get-Credential "litwareinc\pilar"

Test-CsDialInConferencing -TargetFqdn -UserSipAddress "" -UserCredential $cred1

The commands shown in Example 2 test the ability of a specific user (litwareinc\pilar) to take part in dial-in conferencing on the pool To do this, the first command in the example uses the Get-Credential cmdlet to create a Windows PowerShell credential object containing the name and password of the user Pilar Ackerman. (Because the logon name –litwareinc\pilar -- has been included as a parameter, the administrator only has to enter the password for the Pilar Ackerman account in the Windows PowerShell Credential Request dialog box.) The resulting credential object is then stored in a variable named $cred1.

The second command then checks to see if the user Pilar Ackerman can log on to the pool and take part in a dial-in conference. To carry out this task, Test-CsDialInConferencing is called, along with three parameters: TargetFqdn (the FQDN of the Registrar pool); UserCredential (the Windows PowerShell object containing Pilar Ackerman’s user credentials); and UserSipAddress (the SIP address corresponding to the supplied user credentials).
