Hi everyone! I'm using jssip 3.9.0 and freeswitch 1.10.7.
Trying to make an incoming video call to a jssip client, but on Windows 11 the answer() method doesn't do anything at all. At the same time it does work fine on Mac, Ubuntu or older versions of Windows. Has anyone had the same issue?

Hi Mir,

Well, the answer() method doesn’t inherently do much. You need to attach the audio and video tracks to <audio> and <video> DOM elements to get them to play.

Perhaps something like this:

<audio id=“my_audio”></audio>
<video id=“my_video”></video>

session.answer({
mediaConstraints: { video: true, audio: true }
});

session.connection.addEventListener(’track’, t => {
let elem = undefined;

if(t.track.kind === ‘audio’)
elem = document.getElementById(‘#my_audio’);
else if(t.track.kind === ‘video’)
elem = document.getElementById(‘#my_video’);

if(elem) {
elem.srcObject = t.streams[0];
elem.play();
}
});

An important update. It actually works if i reset camera and mic permissions. But it works only once, until the next reset.

Yeah…

There’s WebRTC, and then there’s the outermost “user interface” to WebRTC, which sadly none of us control.
