On the documentation I found this link, https://developers.telnyx.com/docs/api/v2/call-control/Call-Commands?lang=php
I guess it is the answer() method that collects the user's choice, can you confirm for me? but the statement $call->answer() is made as soon as the phone call starts, how can i wait for the user's interaction?
Hello,
You can use gather command to read user's input. Please check relevant documentation for the same here.
There are three types of gather available:
gather using audio — plays an audio file as a prompt to collect DTMF input,
gather using speak — uses text-to-speech (TTS) as a prompt to collect DTMF input,
gather — collects DTMF without providing a prompt.
Each one these issues a call.gather.ended once the final input can be determined
If you're new to DTMF, you can learn more about them here
