I have a scenario where a Caller called an Agent. Caller and Agent are already engage. How can a 3rd caller(Supervisor) barge in to listen to their conversation.
Thank You,
Simply dial into the conference using TwiML like this:
<Response>
<Dial>
<Conference>conference-room</Conference>
</Dial>
</Response>
you can use the muted attribute if you want the supervisor to hear the conversation, but not be heard:
muted="true"
