From a video perspective it has to support multiple video streams and displaying them (Asterisk doesn't do video transcoding or mixing).</blockquote><div><br></div><div>You mean with a softphone you can't select a single (or several) video among those available, can you ?</div><div>Even with DTMF sequence and some features.conf magic, a user cannot ask to receive a specific video stream ?<br></div><div><br></div><div>(forgive me if my question seems naive or irrelevant but I didn't dare to try or install anything yet)<br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"> From a messaging perspective it has to support the JSON payload that Asterisk is using in ConfBridge.
