Actually I'm trying kurento-one-many example using kurento media server. I had tried to stream only audio so that I could able to get a stable audio stream, but the results are same as in video stream. Voice of the presenter get break(i.e. some word get missed, stream become silent) in between regularly. How could I able to get an stable audio stream (i.e. without missing any word of presenter) using Kurento media server.

If you try the same example with video, does it happen?

Voice is breaking in between continuously over video also, words of the speaker get missed regularly in whole session. 
Actually, i had used these constraints in kurento-utils.js to do audio-video stream through kurento media server.

var MEDIA_CONSTRAINTS = {
audio: true,
video: {
mandatory: {
maxWidth: 128,
maxHeight: 97,
minFrameRate: 10
}
}
};

Here, you can see I had put the frame so small so that it could produce light weight stream. So that our chat session become stable and user could able to get a smooth audio, but the problem is that audio is really very unstable, voice get missed in regular intervals.

You can compare against this public demo. It's an instance of the one2many demo, hosted in the FIWARE lab. I've just checked against that instance, and audio works fine. So I guess "Audio stream in breaking using kurento media server" is just not appropriate. On that matter, please have a look at this post.

Could you share a bit about your setup? I guess that it must be something about that, like bandwidth or link quality or whatnot, that is braking the quality.

Cheers,

Hello Ivan,

Actually, I had tried your this link and I cant able to get the stream at viewer side. When, I checked the sdp and ICE candidate offer I cant able to see any public IP that get resolved in SDP (i.e. only host type candidates get resolved)

Here I'm attaching presenter and viewer snapshots and console text there you can check the sdp.

I'm getting the same problem when I've hosted Kurento media server. Actually I'm thinking that some ports are block in my firewall that's why I can't able to get the candidate return by stun server.

I think it's a local problem of your firewall, yes, that's why I pointed you to that demo. If you are only getting host candidates, it seems like the STUN requests are being blocked.

For sure sir I'm completely agree with you but could you please tell me what port has to be open to run this hosted example beyond my firewall. Actually, this is true that application run fine without firewall but I want to know whats port this application is using that has to be open.
