I found the problem. I am sending Refer request with SIPP so writing wrong R-URI name address that is already<u> responsible</u> Proxy instead of B2Bua contact name address. Thus , loose_route function re-write RURI and removed top most route header as specified

<div> </div>
</div>
<div dir="auto">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>
