Windows Phone 的 Linphone 崩溃 - System.Exception：RPC 服务器不可用。（HRESULT 异常：0x800706BA）

Question

我得到了 Windows Phone 的 git 源代码 (linphone-wp)。我通过了自述文件中的所有步骤并成功编译了该项目。我正在使用 Visual Studio 2013。我部署了应用程序。我可以访问任何屏幕，但在我输入真实 SIP 帐户的有效连接数据并成功注册 SIP 帐户后，我收到此错误和应用程序崩溃：

   {System.Exception: The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)
   at Linphone.Core.OutOfProcess.Server.get_LinphoneCore()
   at Linphone.Model.LinphoneManager.get_LinphoneCore()
   at Linphone.Dialer.IsAccountConfigured()

   at Linphone.Dialer.OnNavigatedTo(NavigationEventArgs e)

   at System.Windows.Navigation.NavigationService.CompleteNavigation(DependencyObject content, NavigationMode mode)
   at System.Windows.Navigation.NavigationService.<>c__DisplayClass7.<NavigateCore_StartNavigation>b__4()}

启用本机代码调试模式后：

First-chance exception at 0x6B319D91 (libantlr3c.dll) in HeadlessHost.exe: 0xC0000005: Access violation reading location 0x00000034.
Unhandled exception at 0x6B319D91 (libantlr3c.dll) in HeadlessHost.exe: 0xC0000005: Access violation reading location 0x00000034.

调用堆栈：

我在模拟器和真实设备 (Lumia 640 XL WP8.1 Update 2) 上都试过了，但我得到了同样的错误。

phone 上的日志不包含任何错误消息。

如果我输入密码错误，则会收到 "bad credentials" 消息。只有在 SIP 服务器上注册成功后才会发生崩溃。

请帮我解决这个问题。欢迎任何建议。

Answer 1

经过长时间的调试，我找到了问题的原因。该问题与

中配置的推送通知功能有关

linphone-wp\Linphone\App.xaml.cs

// Initialize the push channel 
InitPushChannel();

// Initialize the task to listen to incoming call notifications on the push channel 
InitHttpNotificationTask();

我没有使用推送通知服务，所以我评论了上面的代码并解决了问题。
