<p>Hello,</p>
<p>the unresolvable destination should be triggered when the dns
server failed to resolve the hostname in r-uri and in this case
it's clear it's an invalid one being a contact for webrtc. You are
not handling correctly the devices connected over websocket, you
have to deal with them as with devices behind the nat, so you add
a contact alias and handle the parameter in r-uri for requests
within dialog -- look at default kamailio.cfg how the nat
traversal part is done.</p>
<p>Cheers,<br>

that the package that arrives at the terminating PCSCF has
an unresolvable request URI due to the websocket connection.</font></div>

guess the terminating SCSCF replaces the request URI with

How can I get over this problem ? Any ideas are welcome.<br>
