问题
I have a twilio number that can process incoming calls with twiml. These incoming calls expect the recipient to press some digits after the call is connected.
If I were making an outgoing call, I could use the sendDigits attribute of a <Dial> tag. However, I can't figure out how to do this in response to an incoming call.
If I were receiving the call in a web client, I could use connection.sendDigits
Is there a way to do this in just twiml? Should I just play a recording file of various DTMF tones?
Edit: To clarify, I'm receiving calls from another automated system that expects additional numbers to be dialed after the call is connected.

Turns out the way to to do this is by using the <Play> twiml tag, which accepts a digits attribute.
<Play digits="94"></Play>
