We used to run a conference server on a PII 400Mhz with 512MB of RAM. We had 2 separate conference rooms with 15 users each (30 simultaneous) calls with no problem. We have since upgraded it to a P4 2.0Ghz with 1GB of RAM (just because it was getting old) and it still works just fine with even higher call volumes. No degradation of quality either that we can see.

Seshu, Why not contact the folks at Softel, Inc. ? They just posted to -biz a few days ago that they now offer a standalone solution that allows 100 simultaneous callers based on Asterisk with no issue. I'm sure they stand behind their product.

For each member in a meetme conference, asterisk needs to decode their audio, mix audio from every other member, and then encode that mixed audio. The mixing operation is O(n^2). It's much simpler than the encoding, but as the number of users goes up, it should become the dominant operation. So, if you have N users in a meetme conference, you need to do (for each frame, more or less): N decodes, N encodes, N*(N-1) mixes. Where N = 100, that's 9900 mixing operations. If N were 200, that would be 39,800 mixing operations. Also, if asterisk is just bridging calls, it's generally not also transcoding, so it's capacity to do simple things with calls is going to be much higher than it's capacity to conference, especially with meetme. -SteveK>Though your solution looks impressive and probably is >the best for upto 30 simultaneous calls, I am more >interested in knowing what it takes for Asterisk to be >able to handle the 100 channels I need to run >Simultaneously. > >Seshu Kanuri > >-------------- next part -------------- An HTML attachment was scrubbed...
