java - 在Twilio发起的通话中发送短信或给其他人打电话

是否可以执行以下操作？我尝试过并失败了！

我使用Twilio从某些Java代码发起调用，而我使用的是TwiML。然后，我想启动另一个操作，例如发送SMS，拨打电话或重新发送到另一个servlet。我无法使用其中的任何一个，并且想知道是否是因为Twilio正在发起呼叫，而不是用户在拨打我的Twilo号码？希望我只是愚蠢！这是我在url文件中尝试过的内容（实际数字已替换为xxxx

尝试发送和短信*

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

最佳答案

在使用TwiML给出一个呼叫的响应的同时，您可以通过REST API发起一个新的呼叫。
