<p>The module requires record routing, so if the UPDATE requires to re-enforce Record-Route, then you have to do it. The <code>404 not here</code> is sent typically when a request within dialog comes without Route header.</p>
<p>I was aware that only NOTIFY requires to re-enforce Record-Route, but can be also a matter of UA implementation to want it for other requests. Without Record-Route/Route headers in the SIP requests, the topos module does not work.</p>
