Hello,<br><br>Few years ago, Dutch Internet Society released a very good application to test for protocol and communication app blocking, the application have not been maintained for some time now, but is still accessible under <a href="http://open.internet.nl">open.internet.nl</a>. I think it will be a good idea to integrate the tests this application does into OONI probe, do you think this is possible?<br><br>The <a href="http://open.internet.nl">open.internet.nl</a> tests for: &quot;VOIP (SIP and Skype), Whatsapp (XMPP), YouTube, BitTorrent and Spotify. And the related protocols RTSP, DNS, RTP and RTCP.&quot;<br><br>Regards,<br>Hanna.<br>
