Customer has installed the trial version on Concert on their network and would like to tweak it for best performance
1-      First, we would not recommend to use Linear, even though it is offered inthe client and server. Linear encoding is a way of encoding audio into digitalwithout using any type of compression. In other words every audio streams isfull bandwidth and 10 clients on using linear codec could probably overload youserver (standalone or virtual)
2-     Second, depending how you plan to use Concert, we would recommend youeither use Speex encoding or G.722 encoding. Speex uses less bandwidth but hasmore latency (the encoding takes more time than G.722). So if you think thatthere will be Concert users connecting from the Internet, Speex Wideband is the best choice as it offers a good balance between latency andbandwidth
3-     If you plan to use Concert in a closed LAN, then G.722 is a goodchoice. Bit rate is a bit higher than Speex (64kbps vs 42kbps), howeverencoding is faster, therefore lower latency. If you want to even lower thelatency, and once again, you are using Concert in a closed LAN, then along withG.722 at the server, you can change the MAX jitter buffer to 200 ms instead ofthe default 800 ms in the Client (go to config/audio, uncheck simple mode, thenchange max jitter to 200). Other things you cando also to reduce latency is to disable the echo canceller at the client. Ifyou plan to use a fairly good headset at the client (USB), then you don’t needecho cancelling at the client (this takes up a lot of time therefore increase the latency).To disable, go also to config/audio, then uncheck Echo Cancel.
