I read lots of articles about Twilio conference call. I created a php function which creates a Twilio conference which can add any one who have access to that link to the Conference with this link. so then I read this article about Dialing Multiple Numbers Simultaneously with Twilio.
This article shows how to dial multiple clients or numbers in the same time but the first one who accept the call will connect while the others will be hung up on.
<?xml version="1.0" encoding="UTF-8"?>
<Response>
<Dial>
<Number>877-555-1212</Number>
<Number>877-999-1234</Number>
<Number>877-123-4567</Number>
</Dial>
</Response>
So now my question is that can I add all of them to a conference call troughs a twilio php function?
I also checked this question on stack overflow but the different is that I am using TwiML and then I thought maybe there is a function to add all clients to same room whe he/she calls a list of them.
$dial->conference('My conference', array(
'startConferenceOnEnter' => True,
'endConferenceOnExit' => True
));
