Transfers the current session to another party without consultation.

Namespace: Microsoft.Office.Interop.UccApi
Assembly: Microsoft.Office.Interop.UccApi (in microsoft.office.interop.uccapi.dll)

Syntax

'Declaration
Sub BlindTransfer ( _
    pUri As UccUri, _
    pOperationContext As UccOperationContext _
)

void BlindTransfer (
    UccUri pUri,
    UccOperationContext pOperationContext
)

void BlindTransfer (
    UccUri^ pUri, 
    UccOperationContext^ pOperationContext
)

void BlindTransfer (
    UccUri pUri, 
    UccOperationContext pOperationContext
)

function BlindTransfer (
    pUri : UccUri, 
    pOperationContext : UccOperationContext
)

Parameters

  • pUri
    A value of the IUccUri* (UccUri, for a .NET application) type. This specifies the SIP URI of the party to which the transfer is made.
  • pOperationContext
    A value of the IUccOperationContext* (UccOperationContext, for a .NET application) type. The default value is NULL. This specifies an application-defined context for this asynchronous request.

Remarks

This is an asynchronous request. An application can expect the corresponding response in an event (OnIncomingTransfer) as defined in _IUccSessionCallControlEvents.

Win32 COM/C++ Syntax

HRESULT BlindTransfer
(
   IUccUri* pUri,
   IUccOperationContext* pOperationContext
);

Note

In a Win32 application, the return value of a method or property is always an HRESULT value indicating the status of the call to the interface member. Any result of the operation is returned as a parameter marked with the [out, retval] attribute. In contrast, in a .NET application the HRESULT value indicating an error condition is returned as a COM exception and the [out, retval] parameter becomes the return value. For the UCC API-defined HRESULT values, see Unified Communications Client API Error Messages.

Example

The following example executes a blind transfer on the current active audio/video session.

/// <summary>
/// The current call is transferred to the
/// telephone represented by the destination URI
/// </summary>
/// <param name="sessionToTransfer">IUccSession session To Transfer </param>
/// <param name="bstrDestinationUri">string destination URI</param>
/// <param name="iOperationId">int passed as operation context</param>
public long BlindTranfer(
    IUccSession sessionToTransfer,
    string bstrDestinationUri,
    int iOperationId)

{
    IUccSessionCallControl sessionCC = sessionToTransfer as IuccSessionCallControl;

    long hr = 0;
    if (sessionCC != null)
    {
        //advise for session call control events on the current session
        UCC_Advise<_IUccSessionCallControlEvents>(sessionCC, this);
        try
        {
            UccOperationContext pOperationContext = new UccOperationContext();
            pOperationContext.Initialize(iOperationId, null);
            UccUriManager UccpUriManager = new UccUriManagerClass();
            UccUri u = UccpUriManager.ParseUri(bstrDestinationUri);
            this.pSessionCC.BlindTransfer(u, pOperationContext);

        }
        catch
        {
            hr = -1;
        }
    }
    return hr;

}
