Trying to process a call from an extension and do some stuff in our API via REST post using Pivot in a call flow. I am returning proper TwiML from our API, and <Say> command works, but <Dial> does not. I would like to use the <Dial> command, based on the result of our REST API processing... May be it's unsupported? If so - is there a resource to lookup all available TwiML commands that are supported? Here is the "Response" that is successfully interpreted by the Pivot: <?xml version="1.0" encoding="UTF-8"?> <Response> <Say voice="woman" language="en-gb">Thank you, you may hang up now!</Say> <Hangup/> </Response> And this one reads the <Say> portion but does not dial 0 :( <?xml version="1.0" encoding="UTF-8"?> <Response> <Say voice="man" language="en-gb">Terribly sorry, but something went wrong. Please stay on the line, connecting to front desk.</Say> <Dial>0</Dial> </Hangup> </Response>
