我在工作笔记本 Linux mint 19.3 Cinnamon ( ) 上安装 Microsoft Teams 应用程序时遇到问题5.4.0-54-generic #60~18.04.1-Ubuntu SMP Fri Nov 6 17:25:16 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux。其中安装了 docker、virtualbox 和 barracudavpn 等。
应用程序可以安装，可以启动，我可以毫无问题地写消息，但无法拨打电话。当我尝试呼叫某人时，1-3 秒后呼叫失败，并显示“抱歉，我们无法接通您”。
该应用程序适用于我的其他同事（运行当前的 Debian 和 Ubuntu）。它甚至可以在我装有 Mint 20 的私人笔记本上运行，但出于某种原因，它无法在我的工作笔记本上运行。
当我查看日志时，journalctl -e我可以看到这些日志（这些是来自呼叫尝试持续时间的日志）：

有人能解释一下那里发生了什么吗？什么可以触发这些变化？在我同事的笔记本和我的私人笔记本上，尝试拨打测试电话时没有日志。这让我想到问题在于这种对网络设备的操纵。现在我的解决方法是在浏览器中使用 Web 应用程序……它可以工作，但不具备桌面应用程序的所有功能（例如自定义背景、同时查看多个呼叫服务员的视频……）
请有人看一下这个日志并提示我下一步该检查什么吗？
