是否可以执行以下操作？我试过了，失败了！

我使用 Twilio 从一些 Java 代码发起调用，并且我正在使用 TwiML。然后我想启动另一个操作，例如发送 SMS、拨打电话或重定向到另一个 servlet。我无法让这些工作中的任何一个工作，并且想知道是否是因为 Twilio 正在发起呼叫，而不是用户拨打我的 Twilo 号码？希望我只是愚蠢！这是我在 url 文件中尝试过的（实际数字替换为 xxxx

尝试发送短信*

这是 Java 代码 - 我没有使用 Twilio 辅助 API 库，因为它在 Google App Engine 上不起作用* ** * *

在使用 TwiML 响应一个调用时，您可以通过 REST API 发起一个新调用。

看看这个：REST API：拨打电话
