This class does not define any methods.


The MSFT_SIPASMCUSetting class has the following properties.

Uint32 AjaxCompressionLevel

Data type: Uint32

Access type: Read/Write

Required. JPEG compression level for viewers connected to a desktop sharing session using Microsoft Office Communicator Web Access.

The default value is 50. Increasing this value increases the fidelity of the images sent to the browser at the expense of higher bandwidth. Decreasing the value reduces the fidelity of images but also reduce bandwidth usage.

The minimum value for this property is 1 and the maximum value is 100.


Data type: [key] string

Access type: Read-only


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}".


Data type: string

Access type: Read/Write

Required. The IP address to listen on.

The value of this property must be a valid IPv4 address that is represented in the following format: "". The asterisk (*) character can be used instead of an IP address to specify all available addresses that pass through the server.

The value must be a valid IPv4 address represented in the following format: "nnn.nnn.nnn.nnn" or the asterisk (*) character. An FQDN (fully qualified domain name) is not allowed.


Data type: uint32

Access type: Read/Write

Required. The ports on which Application Sharing Server expects to receive messages from SIP peers.

Port 5065 is normally used by incoming SIP listening requests for application sharing.

The minimum value for this property is 1 and the maximum value is 65535.
