    McuDialOutOptions mcuDialOutOptions,
    AsyncCallback userCallback,
    Object state
)

Parameters

• destinationUri
  Type: System.String
  The URI of the entity to call.

• mcuDialOutOptions
  Type: Microsoft.Rtc.Collaboration.McuDialOutOptions
  Optional parameters to customize the dial-out request.

• userCallback
  Type: System.AsyncCallback
  The method to be called when the asynchronous operation is completed.

Exceptions

Remarks

The appearance of the dialed-out to endpoint in the conference roster can be customized by supplying a participant URI and display name in the mcuDialOutOptions object. The MCU may not honor the settings if the asserted identity of the dialed-out to endpoint was communicated to the MCU during the dial-out operation.
