Android Pjsip: Audio Conference Call

Question

I am implementing Audio Conference Call in Android using Pjsip library v2.6. What I have done is:

Call A -> B

Put B on hold

Call A -> C

Re-invite B

The issue I am facing is, I can hear voice from A -> B and A -> C. But there is no voice transmission between B -> C.

I think something is missing related to connection bridge between B -> C but I am not getting any hint for that.

Can any one advice me how to create that or how to proceed?

Thank you in advance...!!

Answer 1

I implemented using this steps and it worked.

All I did is:

Get AudioMedia of B and C and started transmission between them like above mentioned link.
