Hi Nawfel,
The problem is in one of the end points as for a 200 OK calls, the 200
reply and the ACK is end-2-end.
If you have a trace, maybe I can help you to see if there is a
signalling problem.
Regards,
Bogdan

Hello!!
I m new in opensips and i m testing the load balancer cause i need
it to balance calls between 4 asterisk.For the start i make the
following scenario
Cisco gateway inbound ------> opensips ------> asterisk
---------> Cisco gateway outbound
when the call comes to the opensips, the load_balancer forward the
call correctly to my asterisk but the call hangs up after 15 seg
approximately.When i did a ngrep for the sip traffic in opensips, i
realized that cisco gateway inbound never sent the ACK for 200 OK to
opensips .
In the Cisco's logs i saw that the reply of 200 ok is sent directly to
public ip of asterisk but never to opensips server so asterisk still
waiting for the ACK from opensips.
In the same way opensips never receive the BYE packet and the load
never decrease when the call is hanging up.
Cisco gateway opensips asterisk
