我无法在我的 android SIP 应用程序上接听任何电话，我可以在 SIP 服务器上成功注册，我可以发起呼叫并成功邀请其他用户，但我无法接听任何电话。我认为我的 SIP 服务器或设备没有任何问题，因为我能够使用 Sipdroid 应用程序并发起和接听电话。
我的代码如下，基于 SipDemo 示例：
public class WalkieTalkieActivity extends Activity implements View.OnTouchListener {
public static final String TAG = "WalkieTalkieActivity";
public String sipAddress = null;
public SipManager manager = null;
public SipProfile me = null;
public SipAudioCall call = null;

private static final int SET_AUTH_INFO = 2;
private static final int UPDATE_SETTINGS_DIALOG = 3;
private static final int HANG_UP = 4;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.walkietalkie);
ToggleButton pushToTalkButton = (ToggleButton) findViewById(R.id.pushToTalk);
pushToTalkButton.setOnTouchListener(this);
// Set up the intent filter. This will be used to fire an
// IncomingCallReceiver when someone calls the SIP address used by this
// application.
IntentFilter filter = new IntentFilter();
filter.addAction("android.SipDemo.INCOMING_CALL");
callReceiver = new IncomingCallReceiver();
this.registerReceiver(callReceiver, filter);
// "Push to talk" can be a serious pain when the screen keeps turning off.
// Let's prevent that.
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
initializeManager();
}
@Override
public void onStart() {
super.onStart();
// When we get back from the preference setting Activity, assume
// settings have changed, and re-login with new auth info.
initializeManager();
}
@Override
