Twilio IVR，TwiML；如何设置按键以拨打特定号码？

我正试图在Twilio网站上用TwiML编写一个IVR。理想情况下，我希望发生的是：

• 按“1”可拨打我设置的号码
• 按“2”键可拨打我设置的号码
• 按“3”键将我带到一个目录。嵌套在数字“3”中，它们会再次显示多个选项，每个选项都会拨一个特定的号码

我想我应该在某个地方使用

action

，但我不知道如何设置拨号的“if”条件。我在编码方面的知识充其量是极其初级的，但这里是我迄今为止所建立的

感谢您致电我们公司，我们是您的第一大商业房地产房源。
按1键销售人员注册并脱颖而出！
按2获得支持！
按3键进入我们的公司目录！

你是对的-你必须对其采取行动。此操作URL将获得用户按下的“数字”，然后您可以采取适当的操作

请参阅下面的示例（action=“/abcxyzDemoIvr”）
