</div><div><br></div>Not sure I understand the remark about the ability to hear and understand everyone in the conference. I have three types of clients who all mix and match in the conference - a PSTN termination provider (with SIP connection/PCMU), SIP softphone (PCMU) and Chrome WebRTC (JsSIP). Since the non-WebRTC end points don't support OPUS, I am not sure using it will help in this case. Will it? <div>
<br></div><div>Also, if I do use OPUS, any advice on how I can limit the bandwidth it uses? I saw opus.conf.xml but it was not clear how to set a bandwidth limit in it. My users are all in controlled bandwidth environments, so I need to make sure a single user does not use more than 80-100 kpbs (in each direction) even if more is available at the time.<div>

Are you not liking the ability to hear and understand EVERYONE in the conference? Makes little sense to me, Sounds like your browser has a bug when PCMU is used at 8k I would really love to know what the problem is and the scenario that triggers it. Its unacceptable to say 'Oh set it to 12000 it fixes it'. The reason you have nobody complaining is they've never really experienced WebRTC properly.<div>
