Get option


What is the point of get option? I assumed when I first looked at using this in my AGI scripts was that it would wait up to n seconds before timing out whilst accepting dtmf digits followed by an escape key? Seems the only way to get digits from a caller is “GET DATA” or WAIT FOR DIGIT which only accepts one…

Should I be using WAIT FOR DIGIT and then concating the digits to a string and waiting for an escape key? Or si there something else I can use?
