I just want to study a successful case for the Webrtc demo (using media mode) in the chapter 6 of book “FreeSwitch 1.6 Cookbook” which uses sip.js (sip-0.7.0.js) in Chrome. So far I fail until now. Please refer to the thread “Webrtc [err] mod_sofia.c 2299 codec negotiation error. Sdp” Regards Smile From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Michael Jerris Sent: Friday, April 08, 2016 3:13 PM To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] OPUS and CPU load Can someone explain why sip would be preferred in this scenario? Is there any real reason?

Setup is chrome (sip.js) ->fs->chrome (sip.js), but end up with fail. Can you share your successful case using Webrtc + opus. (SIP preferred to Verto as signal).

Hi all,,
I have found that the CPU usage with users WebRTC + OPUS is high. With 2vCPUs, 10 users use 25% of CPU. Anyone know if this load is normal?
