Your ACK (as it is for a 200 OK) should be routed based on Route
headers (record route and loose route mechanism). TO better
understand this, please take a look to this webinar:<br clear="none" class="" style="">
<a rel="nofollow" shape="rect" class="" target="_blank" href="http://www.opensips.org/Documentation/Webinars#toc12" style="">http://www.opensips.org/Documentation/Webinars#toc12</a> (
chapter 5.5 )<br clear="none" class="" style="">
<br clear="none" class="" style="">
At INVITE time you should do record_route() and the ACK should
carry the Route headers in order to follow the same path as the
INVITE.<br clear="none" class="" style="">
