BeginEstablish(AudioVideoCallEstablishOptions, AsyncCallback, Object)
Establishes an outgoing call using audio-video call specific options.
public:
IAsyncResult ^ BeginEstablish(Microsoft::Rtc::Collaboration::AudioVideo::AudioVideoCallEstablishOptions ^ options, AsyncCallback ^ userCallback, System::Object ^ state);
public IAsyncResult BeginEstablish (Microsoft.Rtc.Collaboration.AudioVideo.AudioVideoCallEstablishOptions options, AsyncCallback userCallback, object state);
override this.BeginEstablish : Microsoft.Rtc.Collaboration.AudioVideo.AudioVideoCallEstablishOptions * AsyncCallback * obj -> IAsyncResult
Public Function BeginEstablish (options As AudioVideoCallEstablishOptions, userCallback As AsyncCallback, state As Object) As IAsyncResult
Parameters
- options
- AudioVideoCallEstablishOptions
Optional parameters to establish the call.
- userCallback
- AsyncCallback
The method to be called when the asynchronous operation is completed.
- state
- Object
A user-provided object that distinguishes this particular asynchronous operation from other asynchronous operations.
Returns
An IAsyncResult that references the asynchronous operation.
Exceptions
Thrown when the call is not in valid state to perform this operation or does not have valid media provider to bind to or
Remarks
Applications can use AudioVideoMcuDialInOptions property to set MCU dial-in options if this call established with a MCU.
Setting the UseGeneratedIdentityForTrustedConference property to true is only valid in scenarios where the conversation has joined a conference as a trusted application. See ConferenceJoinOptions.
An application can establish multiple AudioVideoCall instances within the same conversation if that conversation joined the conference as a trusted application. In order to establish multiple calls, the application needs to set UseGeneratedIdentityForTrustedConference to true.
Applies to

Call establish options to be used when retrieving call from the park server. This parameter value can be null.
- userCallback
- AsyncCallback
The method to be called when the asynchronous operation is completed.
- state
- Object
A user-provided object that distinguishes this particular asynchronous operation from other asynchronous operations.
Returns
An IAsyncResult that references the asynchronous operation.
Exceptions
orbit
parameter is null.
options
parameter contains invalid or restricted signaling headers.
Current call is not in a valid state to initiate an establish operation.
