If i check my ACK messages sent from my LB to my proxy, to Route headers is present. So my ack has not been forwarded to my SBC. So i can't route all subsequent INVITE messages without using dispatcher for ACK messages.
ACK messages are in the same INVITE transaction ? My SBC is asterisk, and does not insert Record-route headers. Is it a normal behaviour for an SBC ?
