The DTMF element sends digits on a live call - for instance, to automate navigation through an interactive voice response (IVR) menu. If async is set to true, Vobiz sends digits in the background and the call moves to the next XML element as soon as the first digit is sent. Use the character w to add a 0.5-second delay and W for a 1-second delay. Allowed values: 1234567890*#wW
