Hi Alex,
<div><br>
</div>
<div>I got your answer about loose route earl mesagess , saved and still keeping it. I try to figure out , what s the best way handle refer message with kamailio if there is a route header. </div>
<div><br>
</div>
<div>When there is route header more than one , smth is going wrong. </div>
<div><br>
</div>
<div>Today , I worked so many cases , all of them may be mixed in my mind. </div>
<div><br>
</div>
<div>I will work on it again.

<div>Hi,
<div><br>
</div>
<div>First, a proxy should only remove the topmost Route headers whose URI domains correspond to addresses the proxy perceives to be its own, not another element’s. Are you sure that is not a possibility in your case?</div>
<div><br>
</div>
<div>Second, the loose_route() should set the network and transport-layer next-hop destination ($du) to the next Route hop. However, if another Route hop is not present because all of them have been consumed by the proxy on the basis that the proxy perceives
them to correspond to itself, then it will consume the RURI domain to determine the final hop. </div>
<div><br>
</div>
<div>I think there is something missing with regard to the actual content of the Route hops and their relationship to your Kamailio instance.</div>
