calls would not be TDM it would be ip-ip calls. Ok G711 uses less CPU than other codecs,how can i utilized multiple threading/profiles or any other options to scale ? as it would be an incoming call always on FS. Regds Sam On Tue, Jan 4, 2011 at 3:53 PM, Steven Ayre <steveayre@gmail.com> wrote:
That will still involve transcoding. FS must combine all speaking channels into a single stream that can be sent to the conference members. That can't be done in a compressed audio format, so it must convert G711 to L16 for each speaking member, combine those pieces of audio, then convert L16 back to G711 to send to the conference members. Additionally, since the conference members are not necessarily all using the same codec that last transcoding step will occur once for each member, not just once for the conference. Your best bet is to use a codec that uses as little CPU for transcoding as possible - in software I'm not sure which is best there (G711 is simple so possibly a good choice), in hardware Sangoma D100/D500 would almost all the processing off the CPU.

Ok if i remove transcoding out of the picture and all conf are running on g711, what rest would matters ?

It's the transcoding that will kill you. If that's truly needed, you may want to look into multiple machines handling transcoding and then
bridging
into the conference, or the new transcoding hardware from sangoma. -Avi On Tue, Jan 4, 2011 at 9:55 AM, Sam <u2nsam@gmail.com> wrote:
hello,
how to increase the scalability / performance of the conference .
Are there any parameters to be observed that could do a trick ?
The scenario would be multiple conferencing bridges and multiple codecs involved.
Is is possible to multiple threading of profiles for conferences so
that
it gets the scalability ?
