You have to do it using a MeetMe conference.

for example, in extensions.conf you could have:

[conference]
; single-digit conf numbers
exten => _X,1,MeetMe(${EXTEN}|dq)
exten => _X,2,Hangup
; multi-digit conf numbers
exten => _X.,1,MeetMe(${EXTEN}|dq)
exten => _X.,2,Hangup

and then in the Manager API you redirect both legs of your established
call at once using Channel and ExtraChannel:

Action: Redirect
Channel: <first channel>
ExtraChannel: <second channel>
Context: conference
Exten: <confnum>
Priority: 1

You have to do them both at once, otherwise you would drop one channel
when the other lets go of it to join the conference.

You can then add any other callers to the same conference as required.

Hope this helps
Cheers
