<p>Hello David,</p>
<p>did I got your correctly that another Kamailio "downstream" also uses the uac module for rewriting?</p>
<p>In this case your guess might be correct, that the rr and uac modules are confused because of the two same headers in one Route header.</p>
<p>Two workarounds:</p>
<p>- set other header name in uac with rr_from_store_param and rr_to_store_param <br>
</p>
<p>- use the dialog module and use restore_mode dialog to get rid of the Route header</p>
<p>Cheers,</p>
<p>Henning<br>
