我有一个具有自我转移功能的b2b呼叫。如果没有应答或座席变得忙碌而无法接听电话，我想重定向到另一个自由座席。我已为传出呼叫分支订阅了ProvisionalResponseReceived，还订阅了StateChanged。因此，我可以看到呼叫何时响铃以及何时从响铃过渡到终止。在呼叫进入终止状态之前，如何将该呼叫转移/转发给另一个座席。有什么方法可以计算出振铃持续时间？还是在我进一步转移之前设置响铃限制？
// Create the outbound call between UCMA and the agent.
_outboundAVCall = new AudioVideoCall(_outboundConversation);
// Register for notification of the StateChanged event on the outbound call.
_outboundAVCall.StateChanged += new EventHandler<CallStateChangedEventArgs>(outboundAVCall_StateChanged);
_outboundAVCall.ProvisionalResponseReceived += new EventHandler<CallProvisionalResponseReceivedEventArgs>(OnOutProvisionalResponseReceived);
//_outboundAVCall.
InitiateBackToBackCall(incomingCall, _outboundAVCall);
_outboundCallLeg = new BackToBackCallSettings(outboundCall, _destinationSipUrit);
incomingCall.StateChanged += new EventHandler<CallStateChangedEventArgs>(inboundAVCall_StateChanged);
incomingCall.ProvisionalResponseReceived += new EventHandler<CallProvisionalResponseReceivedEventArgs>(OnInProvisionalResponseReceived);
// incomingCallLeg.StateChanged += OnCallStateChanged;
// Create a new conversation for the incoming call leg.
_inboundConversation = new Conversation(incomingCall.Conversation.Endpoint);
_inboundCallLeg = new BackToBackCallSettings(incomingCall);
LogHelper.Log(LogTarget.FileEvent, "Status of incomming call:" + incomingCall.State.ToString());
LogHelper.Log(LogTarget.FileEvent, "Status of incommoutgoing call:" + outboundCall.State.ToString());
// Create the back-to-back call instance.
// Note that you need a Destination URI for the outgoing call leg, but not for the incoming call leg.
_b2bCall = new BackToBackCall(_inboundCallLeg, _outboundCallLeg);
// Begin the back-to-back session; provide a destination.
try
{
IAsyncResult result = _b2bCall.BeginEstablish(BeginEstablishCB, _b2bCall);
/* IAsyncResult result = _b2bCall.BeginEstablish(
delegate(IAsyncResult ar)
{
_b2bCall.EndEstablish(ar);
_waitForB2BCallToEstablish.Set();
}, _b2bCall);*/
}
catch (InvalidOperationException ioe)
{
LogHelper.Log(LogTarget.FileEvent, "_b2bCall must be in the Idle state." + ioe.Message.ToString(),1);
}
_waitForB2BCallToEstablish.WaitOne();

我必须添加代码来处理将要发生的异常
private void SelfTransferCompleted(IAsyncResult asyncResult)
{
Exception exceptionCaught = null;
// bool exceptionEncountered = true;
try
{
_flow.Call.EndTransfer(asyncResult);
//Self Transfer has completed. successfully.
exceptionEncountered = false;
LogHelper.Log(LogTarget.FileEvent, "IVR Menu Ended self tranfer for call>" +_flow.Call.CallId);
// cleaning up atten
string sqlstring = "update astsxqueue set uniqueid ='" + _server.b2bCallDelId + "' where uniqueid='" + _flow.Call.CallId + "';";
LogHelper.Log(LogTarget.FileEvent, sqlstring);
_server.mconnector.Mysqlqueryruner(sqlstring);
}
catch (OperationTimeoutException orte)
{
LogHelper.Log(LogTarget.FileEvent, "IVR SelfTransferCompleted Operation Timeout Exception: " + orte.ToString(), 2);
exceptionCaught = orte;
exceptionEncountered = true;
LogHelper.Log(LogTarget.FileEvent, "IVR SelfTransferCompleted Trying to transfer to other agent...", 2);
RetrieveCallAfterTransferFailure();

LogHelper.Log(LogTarget.FileEvent, "IVR SelfTransferCompleted Waiting for transfer to complete...");
_server._waitForTransferComplete.WaitOne();
LogHelper.Log(LogTarget.FileEvent, "IVR SelfTransferCompleted Transfer completed.");
}
catch (FailureResponseException frte)

exceptionCaught = rte;
exceptionEncountered = true;
LogHelper.Log(LogTarget.FileEvent, "IVR SelfTransferCompleted Trying to transfer to other agent...", 2);

}
}
private void RetrieveCallAfterTransferFailure()
{
// Take the call off of hold after a transfer fails.
LogHelper.Log(LogTarget.FileEvent, "IVR Trying to retrive from Self transfer ...", 2);
try
{
_flow.BeginRetrieve(retrieveResult =>
{
try
{
LogHelper.Log(LogTarget.FileEvent, "IVR Trying to retrive from Self transfer ...", 2);
Thread.Sleep(1000);
_flow.EndRetrieve(retrieveResult);

LogHelper.Log(LogTarget.FileEvent, "IVR Call is retreived time passed...", 1);

// _flow.EndRetrieve(retrieveResult);
// _speechSynthesizer.Speak("A green agent is busy. Please retry your option!"); //TEXT TO SPEEECH!
// SpeakMenuOptions();
// toneController.ToneReceived += toneController_ToneReceived;
}
catch (RealTimeException rtex)
{
LogHelper.Log(LogTarget.FileEvent, "IVR Failed retrieving call." + rtex);
}
},
null);
}
catch (InvalidOperationException ioex)
{
LogHelper.Log(LogTarget.FileEvent, "IVR Failed retrieving call."+ ioex);
}
}
添加以上代码后，我就可以使用它。
谢谢。
