IAsyncResult ^ BeginEstablish(AsyncCallback ^ userCallback, System::Object ^ state);public IAsyncResult BeginEstablish (AsyncCallback userCallback, object state);member this.BeginEstablish : AsyncCallback * obj -> IAsyncResultPublic Function BeginEstablish (userCallback As AsyncCallback, state As Object) As IAsyncResultParameters
- 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.
Applies to
BeginEstablish(CallEstablishOptions, AsyncCallback, Object)
Establishes an outgoing call with given options.

- options
- CallEstablishOptions
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 options parameter contains invalid or restricted signaling headers. Also thrown when
the call is used as a third party call controller with custom MIME parts or with early media support.
Thrown when the call is not in valid state to perform this operation or does not have valid media provider to bind to.
Applies to

The optional parameters to be used when establishing 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
destinationUri parameter is null, empty or invalid sip URI or tel URI.
options parameter contains invalid or restricted signaling headers.
