Great question — answering as the UphillTech team:
I usually use TwiML for making a conference call, It's simple to implement. $my_conference = "My Conference"; $statusCallbackUrl = "https://example.net/Welcome/conference_control"; // call back url <Response> <Dial> <Conference beep="false" statusCallback="<?php echo $statusCallbackUrl; ?>" statusCallbackEvent="start end join leave mute hold" endConferenceOnExit="true" startConferenceOnEnter="true"> <?php echo $my_conference; ?> </Conference> </Dial> </Response> Hopefully, it will help you.
