Specifies the encryption settings for enterprise voice.

The property values for the MSFT_SIPVOIPEncryptionSetting class map to the settings found on the General tab of the Pool Properties dialog box. You can access these values in the Office Communications Server 2007 R2 Administration Tool by right-clicking the name of a Standard Edition server or Enterprise Edition pool, pointing to Properties, and then clicking Pool Properties. In the Pool Properties dialog box, click the Media tab. Note that these settings apply only to the specified pool or server.

The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties. Properties are listed in alphabetic order, not MOF order.

class MSFT_SIPVoIPEncryptionSetting
{
  [key] string Backend;
  string EncryptionLevel;
  [key] string InstanceID;
};

Methods

This class does not define any methods.

Properties

The MSFT_SIPVoIPEncryptionSetting class has the following properties.

  • Backend
    Data type: [key] string

    Access type: Read-only

    Required: When accessing data from any role that belongs to a pool. This property must be empty when accessing data from the Edge Server or Proxy Server role.

    This property identifies the instance of SQL Server that manages the back-end database for Office Communications Server.

    The value for this property depends on the topology of Office Communications Server.

    Topology

    Value

    Standard Edition

    (local)\rtc

    Enterprise Edition

    (consolidated or expanded configuration)

    computername\instancename

    or

    computername

    For Enterprise Edition, computername identifies either the FQDN or the NetBIOS name of the host computer for SQL Server and instancename identifies a named instance of SQL Server on the host computer. The value computername by itself specifies the default instance of SQL Server on the host computer.

    The Backend property does not map to the Pool Properties dialog box.

  • EncryptionLevel
    Data type: string

    Access type: Read/Write

    Required. Specifies the level of encryption to apply.

    Value

    Description

    SupportEncryption

    Inbound and outbound VoIP connections to the A/V Conferencing Servers in this pool can be encrypted using Secure Real-time Transport Protocol (SRTP).

    RequireEncryption

    Inbound and outbound VoIP connections to the A/V Conferencing Servers in this pool must be encrypted using SRTP. If you require encryption, a participant whose computer is not capable of SRTP encryption is unable to join any audio/video conferences that are hosted by the A/V Conferencing Servers in this pool.

    Office Communicator 2007 R2 clients support SRTP encryption. Legacy clients, such as Office Communicator 2005, support 3DES encryption.

    DoNotSupportEncryption

    Inbound and outbound VoIP connections to the A/V Conferencing Servers in this pool are not encrypted.

    The value of this property is not case-sensitive.

    The default value is RequireEncryption.

    The EncryptionLevel property maps to the Encryption level dropdown box in the Pool Properties dialog box.

  • InstanceID
    Data type: [key] string

    Access type: Read-only

    Required. A GUID value that uniquely identifies an instance of this class.

    The GUID must be encapsulated between the "{" and "}" braces; for example: "{01234567-0123-4567-89AB-CDEF01234567}".

    The InstanceID property does not map to the Pool Properties dialog box.

Remarks

This class gets and sets information at the following level: SQL.

Only one instance of this class can be present in the pool.

You should keep the value of EncryptionLevel set to RequireEncryption.

Instances of this class support the following interface methods:

  • Provider::EnumerateInstances();

  • Provider::GetObject();

  • Provider::PutInstance();

    Where PutInstance() supports the following flags:

    • WBEM_FLAG_CREATE_ONLY

    • WBEM_FLAG_UPDATE_ONLY

    • WBEM_FLAG_CREATE_OR_UPDATE

Requirements

Server: Installed on computers serving the following roles: Administrative Tools Server, Audio/Video Conferencing Server, and Front End Server.

Namespace: Defined in \root\cimv2.
