The INVITE request to End-point B generated with append_branch() within openSIP. 
So how openSIP knows to generate a CANCEL message when one End-point answers the call?

The cancel should go out automatically. You don't need to generate it.

- openSIP received two 180 messages from both End points A and B.

- End-point A answers, and sends a 200OK to openSIP

Then, I need to sends a CANCEL message to End-point B.

Which one of the functions I can use:  sl_send_reply( ) or  t_reply( ) ?

I assume the function should be called in onreply_route block !!
