Tapi 3和C＃第一次調用後沒有事件觸發

我在C＃中爲地面線路電話編寫TAPI 3.0應用程序。我的目標是接收和記錄呼叫。到目前爲止，在我的代碼中，第一次調用一切正常，所有事件都觸發。Tapi 3和C＃第一次調用後沒有事件觸發

但不幸的是，所有後續調用完全由TAPI第一個電話後忽略

沒有任何事件觸發，直到我再次重新啓動應用程序。

一件事，我已經找到了，而如果我重置基於Tapi例如它可以解決我的問題，谷歌搜索，

誰能告訴如何重置基於Tapi對象？

這裏是我的代碼

我想避免下面的第一個解決方案，如果可以的話，下面的第二個解決方案不適合我。你自己找到了解決方案嗎？ – Rob

沒關係，我找到了解決辦法，看到下面的答案 – Rob

對於這個問題，我使用基於Tapi通過Julmar寫的託管C＃的包裝，可以是downloaded，通過採用該試樣來電也以.wav F爲recroded ormat

TPhone tphone;

哇，這被評爲awer，但我測試了你的代碼，它甚至沒有編譯...'TapiPhoneEventArgs ev = E作爲TapiPhoneEventArgs;' 不會工作和'如果（CallStat == CallState.Offering）'CallStat甚至不存在...''lockAnswer'也不存在。爲什麼我甚至會打擾它嘗試... – sLowDowN

你有沒有打過電話：

tobj.Shutdown(); 
initializetapi3();

接收TAPI3Lib.CALL_STATE.CS_DISCONNECTED事件之後（或任何事件之後）？因此，例如：

case TAPI3Lib.CALL_STATE.CS_DISCONNECTED: 
    status("Disconnected"); 
    tobj.Shutdown(); 
    initializetapi3(); 
    break;

那是因爲在第一個打電話給你的呼叫狀態的空閒時間小於毫秒。

爲什麼不用'counter ++ <2'？因爲'++ counter <3'只會是真的兩次 – sLowDowN

的解決方案是等到TAPI callstate斷開事件，並且一旦發生了這種情況：

一個）UnRegisterDeviceForEvents與斷開事件相關聯的裝置地址，然後

b）中RegisterCallNotifications相關聯的裝置地址與斷開事件
