<br>
- openSIP received two 180 messages from both End points A and B.<br>
- End-point A answers, and sends a 200OK to openSIP<br>
Then, I need to sends a CANCEL message to End-point B.<br>
<br>
Which one of the functions I can use: sl_send_reply( ) or t_reply( ) ?<br>
I assume the function should be called in onreply_route block !!<br>
<br>
Thanks,<br>
RR<br>
