Using PAGD is the controlled way of collecting digits from the caller. You could rely on the events from the event socket PAGD does a lot of the dirty work for you, like handling invalid input, etc.

I notice that there are DTMF events that come over the event socket. Is it best practice to use the play_and_get_digits dialplan app to collect digits or is collecting the digits using the DTMF events a better way?
