Hi Bogdan, Thank you for your prompt response. I'm sorry I couldn't send the trace before but I had some problems with my network. Also I've change the IP Address schema. The call is originated from 192.168.2.150 to 192.168.2.165:5060 which is the opensips address. Currently, the load balancer is configured to redirect the calls to 192.168.2.165:5061 or 192.168.2.165:5062. In the call I'm sending the INVITE was redirected to 5061.
The you will see that the ACK is not redirected to the destination.
