Voip conference implementation

Question

Hi I need some information on how to implement Voip (RTP) audio conference. I need an algorithm description. Can someone point me to relevant resource on web.

Answer 1

FreeSWITCH is a open source, which has a support for Audio conferencing upto 10,000 simultaneous calls (may be more). You may not find any conferencing algorithm lying open. Search for white papers on audio mixing.

Answer 2

The RFCs are the obvious starting points.

• https://www.rfc-editor.org/rfc/rfc3550
• https://www.rfc-editor.org/rfc/rfc3551

I'm not sure what algorithms you are asking for, but the RFCs contains algorithms for RTCP and other things.
