<p>UPDATE requests should be routed fine as requests within active dialogs.</p>
<p>This looks like some misconfiguration or a broken SIP entity somewhere, because the R-URI for UPDATE2 looks like a Route header URI, not a contact URI. That can happen because Kamailio considers the R-URI (after TOPOS processing) points to itself.</p>
<p>You need to get the pcap with the SIP traffic for the entire call, from initial INVITE to the UPDATE requests and email to <a href="mailto:sr-users@lists.kamailio.org">sr-users@lists.kamailio.org</a> to get assistance, because it does not seem to be about a C code issue. If I am wrong, then this item can be reopen.</p>
