在Android的Linphone呼叫SDK中接收来电时出错?

标签: android linphone linphone-sdk voip-android

一段时间以来,我一直在android应用程序中实现VoIP呼叫功能,大部分工作已经完成,但是当用户通过该应用程序与另一个用户通话时,大多数情况下,同一个人正在从初始化的地方。

例如,有两个用户 ABC CBA 。当ABC呼叫CBA时,它是正确完成的,但是当情况相反时,即当CBA呼叫ABC时,在Linphone的传入方法中,它将接收远程用户名CBA,这意味着CBA正在接到本身。

如何解决这个问题?我使用错误的方法吗?

我完全没有使用过适用于Android的Linphone Calling SDK,甚至没有更改过它的方法。

下面是用于接收传入呼叫的​​LinphoneService的代码。

public final class LinphoneService extends Service {
    /* Listener needs to be implemented in the Service as it calls
     * setLatestEventInfo and startActivity() which needs a context.
     */

    private final static int NOTIF_ID = 1;
    private final static int INCALL_NOTIF_ID = 2;
    private final static int MESSAGE_NOTIF_ID = 3;
    private final static int SAS_NOTIF_ID = 6;

    public static boolean isReady() {
        return instance != null && instance.mTestDelayElapsed;
    }

    /**
     * @throws RuntimeException service not instantiated
     */
    public static LinphoneService instance() {
        if (isReady()) return instance;

        throw new RuntimeException("LinphoneService not instantiated yet");
    }

    public Handler mHandler = new Handler();

            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(intent);
        }

    }

当服务中有任何以名称LinphoneManager.getLc().addListener初始化的服务中有传入呼叫时,它会侦听传入的呼叫,如果If语句被提及为

if (state == LinphoneCall.State.IncomingReceived) {
                    android.util.Log.d("ServiceStarted", "IncomingCall  Status");
                    onIncomingReceived2(call);
                }

现在在代码底部,有一个方法onIncomingReceived2(LinphoneCall call)。因此,当我从默认方法(即 call.getRemoteAddress())中进行检查时,我得到了与初始化电话相同的用户名。

因此,当我拨打电话时,它是在同一设备上收到的。 如果有人可以提供帮助,我们将不胜感激。 预先感谢。
