Thanks a lot to both for your advice, it has been really useful.<div><br></div><div>Stephen, yes, I am referring to BBB. And I have a question, as far as BBB is not limited by software and we need to run conference larger than 25 we need to scale the hardware. But, I would like to know about the possibility to distribute BBB across multiple servers, how can we do it? do you know if there is any documentation about it?</div>
<div><br></div><div>And about Misheshu comments, I think the licence issue will be a problem. The implementation of G.729 I am talking about is proprietary, not open at all, so we need to find out if it is possible to use it with FreeSWITCH (I am not well versed on the licensing issues, so I will read the licenses and try to understand them).</div>
<div>You can check this comparison table to have an idea about this codec performance,</div><div><br></div><div><img src="cid:ii_13eb05fd6cecc319" alt="Imágenes integradas 1"></div><div><br></div><div>And finally, about audio transcoding. We use BBB and speex for the encoding, but as Stephen said before, maybe the audio is not the only problem we have. We need to run more tests...</div>

<b>Subject:</b> [Freeswitch-users] New codec integration and concurrent calls limitquestions<u></u><u></u></span></p><div><div class="h5"><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Hello everyone,<u></u><u></u></p>
<div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">we are working on a videoconferece platform with freeSWITCH integrated. Now we have a the possibility to try a new codec, proprietary, and we have never gone too deep with freeSWITCH. I have tried to take a look at the wiki but I didn´t find the answer to the next question,<u></u><u></u></p>
</div><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">Is it possible to integrate that new codec into freeSWITCH? according to the codec provider it is a G.279 implementation, with several improvements. Any licence issue? difficulty to achieve the integration? <u></u><u></u></p>
</div><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">On the other hand, we also have another issue. I have checked freeSWITCH wiki trying to find any possible limit for concurrent calls, and according to it,<span style="font-family:"Arial","sans-serif""> it </span><span style="font-size:10.0pt;font-family:"Arial","sans-serif";background:white">doesn't seem to be a limit of SIP but purely the RTP</span>. But with the open source video conference platform we are working now this is limited to 25, and according to the developers it is due to the audio. Do you have any idea about this issue? We have run some test and we go over 25 people in the meeting freeSWITCH uses 125% of CPU (ref. 8 cores machine and each core represent 100% capacity => 800%), is this a normal behavior?<u></u><u></u></p>
