How to add another number to the current call using Twilio?

Question

I am developing a Java application using Twilio. So I was able to create a call between two users. One to one call. But I need to add another person/number to that ongoing call. Like a group call If I needed it. So basically there are two people who are in a call and if the creator of the call (Twilio number user) should be able to add another person to that call. So how can I achieve that? I have checked the conference call.

But the issue is if I did manage to create a conference call with the two numbers, but how can I add another number to that ongoing conference call?

Answer 1

would adding a <Gather> with a long timeout help? You can set any key you decide which would start a function that prompts you to enter a number to dial out.
