無法使用ucma 5.0從pstn轉接來電

Question

我正在為buisienss和UCMA 5.0開發基於skype的自定義IVR系統

在我的應用程序中，我使用begintransfer方法將調用轉移給用戶。 當我從Skype客戶端內部呼叫時，一切正常，呼叫路由正確。 來自pstn網關呼叫的入站呼叫被應答，並且無需異常執行begintransfer，但呼叫不會路由到分機。

這是我的代碼： call.BeginTransfer（）

我不能使用前進（而不是轉移），因為當呼叫尚未建立時，前向工作。 我需要播放錄音並為沒有IVR的轉接而不轉發的來電做出選擇。

我想我在“_toneController_ToneReceived”事件中遺漏了一些東西

我究竟做錯了什么？

public class IVR
{

    private static void _toneController_ToneReceived(object sender, ToneControllerEventArgs e)
        {

            number += getToneString(tone);

            if (number.Length == 3)
            {
                try
                {    
                    CallTransferOptions unattendedTransferOptions = new CallTransferOptions(CallTransferType.Unattended);

                    //  currentCall.BeginTransfer(number, unattendedTransferOptions, TransferCallBack, null);
                    //currentCall.BeginTransfer(number , null,null);//, EndEndpointEstablish, new object());

                    currentCall.BeginTransfer(
                                       number,
                                       new CallTransferOptions(CallTransferType.Attended),
                                       result =>
                                       {
                                           try
                                           {
                                               currentCall.EndTransfer(result);
                                           }
                                           catch (OperationFailureException ofe)
                                           {

                                                   ofe));
                                           }
                                           catch (RealTimeException rte)
                                           {

代碼是正確的。 我在Skype服務器上設置錯誤。 如果傳輸正在運行，則必須在中繼配置中啟用suport 。

重要的提示 ：

Lync Server全局，站點或池中繼配置策略啟用了“啟用引用支持”選項

本地部署的IP網關或由Internet服務提供商（ISP）SIP中繼服務部署的IP網關不支持使用SIP REFER方法
