我正在尝试使用 C++ builder 在 Embarcadero 的 SIP 应用程序上接听电话,但我无法接听。我的情况如下:
我已经制作了一个 Asterisk 服务器,我已经创建了几个帐户来进行测试,并且我已经下载了适用于 Windows 和 Android 的 Zoiper 应用程序。在我设计的应用程序中,我可以调用那些在 Zoiper 中注册的帐户,虽然不是通过事件,但似乎监听器没有监听,我通过调用中的状态更改来完成它。
Java代码是这样的:
SipAudioCall.Listener listener = new SipAudioCall.Listener() {
@Override
public void onCallEstablished(SipAudioCall call) {
call.startAudio();
call.setSpeakerMode(true);
call.toggleMute();
Log.d("on call established", "on call established");
}
@Override
public void onCallEnded(SipAudioCall call) {
finish();
}
};
在 Embarcadero C++ 构建器中,我认为它会是这样的(它不起作用)编译并执行,但事件永远不会发生:
//The Manifest counts as the necessary permissions for Android, Internet and Sip.
_di_JSipAudioCall_Listener audioCall_Listener;
_di_JSipSession_Listener sessionListener;
_di_JSipSession session;
_di_JSipManager;
_di_JSipAudioCall audioCall;
_di_JSipProfile profile;
_di_JString uri;
_di_JString uri_llamada;
void onCallEstablished2(SipAudioCall call);
//The process of profile creation and instantiation of SipManager are programmed
//and compiled and do not give any problem.
audioCall_listener = TJSipAudioCall_Listener::JavaClass->init();
audioCall_listener->onCallEstablished = onCallEstablished2;
sessionListener = TJSipSession_Listener::JavaClass->init();
session = manager->createSipSession(profile,sessionListener);
audioCall = manager->makeAudioCall(uri,uri_llamada,audioCall_listener,15);
void onCallEstablished2(SipAudioCall call)
{
audioCall->startAudio();
audioCall->setSpeakerMode(true);
}
在 Embarcadero C++ builder 中制作的代码有效:
//The Manifest counts as the necessary permissions for Android, Internet and Sip.
_di_JSipAudioCall_Listener audioCall_Listener;
_di_JSipSession_Listener sessionListener;
_di_JSipSession session;
_di_JSipManager;
_di_JSipAudioCall audioCall;
_di_JSipProfile profile;
_di_JString uri;
_di_JString uri_llamada;
//The process of profile creation and instantiation of SipManager are programmed
//and compiled and do not give any problem.
audioCall_listener = TJSipAudioCall_Listener::JavaClass->init();
audioCall_listener->onCallEstablished = onCallEstablished2;
sessionListener = TJSipSession_Listener::JavaClass->init();
session = manager->createSipSession(profile,sessionListener);
audioCall = manager->makeAudioCall(uri,uri_llamada,audioCall_listener,15);
Timer1->Enabled = true;
void __fastcall TMainForm::Timer1Timer(TObject *Sender)
{
if (audioCall->getState() == 8)
{
audioCall->startAudio();
audioCall->setSpeakerMode(true);
}
if(audioCall->getState() == 0)
{
audioCall->endCall();
}
}
至于接听电话的 Java 代码,我在这里找到了 No ringing event on incoming call 和这里 Android Sip incoming Call using Service with Broadcast Receiver的示例,但它们都是基于事件的,这似乎对我不起作用。我也尝试过从 BroadcastReceiver 扩展而来的 IncomingReceiver 类,并且在 Embarcadero 给我带来了问题。
在 Embarcadero 中使用 C++ builder 制作的类(不编译):
class IncomingReceiver: public JBroadcastReceiver{
public:
__fastcall IncomingReceiver();
_di_JSipAudioCall incomingCall;
void onReceive(_di_JContext contexto, _di_JIntent intento);
void accept();
void showIncomingCallGui(_di_JIntent intento, _di_JContext contexto);
};
所以,我的问题是:
为什么事件对我不起作用?
我可以在没有事件的情况下接听电话吗?
如果是这样,没有事件会是什么样子?
如果我无法获得 IncomingReceiver 类怎么办?
