<div>Hi Bogdan,</div><div><br></div><div>Thanks for the answer.</div><div></div><div>I
tried this module, but nothing weird was found. On reply ACK messages
in sngrep capture I see the correct "To/Contact'' header, but in log the

something wrong with the route, it should also be looped without enabled

<br>
The tracing part has nothing to do with the routing on the SIP side. And <br>
usually you end up with SIP loops if, without changing the RURI, you <br>
send the SIP request out, making OpenSIPS to send the request back to <br>
itself (as the destination in RURI still points to OpenSIPS).<br>
<br>
I advice you to try to understand the execution flow via your script by <br>
using the script_trace[1] function and logging the RURI (as $ru)<br>
