BeginEstablishEarlyMedia(AsyncCallback, Object)

Sends a provisional reliable response with a 183 response code SessionProgress; also creates an early dialog.

public:
 IAsyncResult ^ BeginEstablishEarlyMedia(AsyncCallback ^ userCallback, System::Object ^ state);

public IAsyncResult BeginEstablishEarlyMedia (AsyncCallback userCallback, object state);

member this.BeginEstablishEarlyMedia : AsyncCallback * obj -> IAsyncResult

Public Function BeginEstablishEarlyMedia (userCallback As AsyncCallback, state As Object) As IAsyncResult

Parameters

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

IAsyncResult

An IAsyncResult that references the asynchronous operation.

Exceptions

InvalidOperationException

Thrown when the call is not in the incoming state, the remote side does not support reliable provisional response or when early media is already being negotiated.

BeginEstablishEarlyMedia(CallProvisionalResponseOptions, AsyncCallback, Object)

Sends a provisional reliable response with a 183 response code SessionProgress; will also create an early dialog.

public:
 IAsyncResult ^ BeginEstablishEarlyMedia(Microsoft::Rtc::Collaboration::CallProvisionalResponseOptions ^ options, AsyncCallback ^ userCallback, System::Object ^ state);

public IAsyncResult BeginEstablishEarlyMedia (Microsoft.Rtc.Collaboration.CallProvisionalResponseOptions options, AsyncCallback userCallback, object state);

member this.BeginEstablishEarlyMedia : Microsoft.Rtc.Collaboration.CallProvisionalResponseOptions * AsyncCallback * obj -> IAsyncResult

Public Function BeginEstablishEarlyMedia (options As CallProvisionalResponseOptions, userCallback As AsyncCallback, state As Object) As IAsyncResult

Parameters

options

CallProvisionalResponseOptions

Optional parameters to be send on provisional response. 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

IAsyncResult

An IAsyncResult that references the asynchronous operation.

Exceptions

ArgumentNullException

Thrown when the options parameter is null.

ArgumentException

Thrown when the options parameter contains invalid signaling headers.

InvalidOperationException

Thrown when the call is not in the incoming state, the remote side does not support reliable provisional response or when early media is already being negotiated.

BeginEstablishEarlyMedia(Int32, CallProvisionalResponseOptions, AsyncCallback, Object)

Sends a provisional reliable response on the call; will also create an early dialog.

public:
 IAsyncResult ^ BeginEstablishEarlyMedia(int responseCode, Microsoft::Rtc::Collaboration::CallProvisionalResponseOptions ^ options, AsyncCallback ^ userCallback, System::Object ^ state);

public IAsyncResult BeginEstablishEarlyMedia (int responseCode, Microsoft.Rtc.Collaboration.CallProvisionalResponseOptions options, AsyncCallback userCallback, object state);
