I was able to implement call whisper using twilio api (runs/plays message on called parties) end using this.
<Response>
<Dial>
<Number url="call_whisper_url">
415-123-4567
</Number>
</Dial>
</Response>
Where call_whisper_url
contains the <Say>
verb. All good.
But how do I play something on callers end? If I do something like this.
<Response>
<Say>Play for Caller</Say>
<Dial>
<Number url="call_whisper_url">
415-123-4567
</Number>
</Dial>
</Response>
It will first play the message then initiate the call. How can I do it simultaneously, meaning: Twilio will initiate the call while playing the <Say>
verb? Or it is the wrong approach?
