Is there anything wrong/buggy with the implementation of the STUN service in 16.6.1?<br></blockquote><div><br></div><div>In that specific version? No. That code itself hasn't been touched in years, so the problem applies to every version. Using the defined STUN server to get a server reflexive ICE candidate is a blocking process. If the server isn't reachable or is extremely slow then it has to wait until a timeout occurs, causing a delay.</div></div><div><br></div>-- <br><div dir="ltr" class="gmail_signature"><div dir="ltr">Joshua C.
