普通的旧 TwiML `Dial` 动词和嵌套在 `Dial` 中的单个 `Number` 之间有什么区别吗？

Question

Other than one being slightly more verbose than the other, functionally is there any difference between these two TwiML blocks, assuming there is no additional configuration? I was unable to find anything in the docs.

<?xml version="1.0" encoding="UTF-8"?>
<Response>
  <Dial>111-111-1111</Dial>
</Response>

<?xml version="1.0" encoding="UTF-8"?>
<Response>
  <Dial>
    <Number>111-111-1111</Number>
  </Dial>
</Response>

Answer 1

You are right, both TwiML files are equivalent.
