I understand the complexity here. I guess I was really trying to get some empirical data or some ballpark idea as to how many conference lines a reference CPU unit can handle. Right now I'm not sure if it is 10, 100, or maybe even 1000!? For most practical usage where callers are from landline/mobile phones, I suppose narrow band should be sufficient and there should not be any transcoding in this case. Cheers.

I don't mean to be overly pedantic here, but the default configurations may allow for the creation of up to 100 conferences of each type, but in essence no conference is actually created until the first caller calls a given conference. That conference remains active until the last caller disconnects from the conference. Each conference runs the audio stream at the given rate it is configured for (i.e. narrowband), and thus has to manipulate the sample rates and perform transcoding as necessary upon non-matching media. Thus there is no simple way to calculate how many conferences you can fit on a server of given configuration X, as there are far too many variables at play for each configuration even.

The out-of-box default configuration creates 100 conference rooms for four different quality levels: narrow band, wide band, ultra-wide band and cd quality. I think you can change the numbers as you wish inside dialplan/default.xml.
I"ve been curious about the CPU usage for conference calls. Is it a linear function of phone lines? For example, for AWS small instance (1 EC2 compute unit), how many concurrent conference lines can it support?
I also did a test on the different quality level. From regular PSTN lines and cellular network, I cannot seem to tell the differences. Can someone confirm?
Cheers.

hi,
I am working on Freeswitch Conference functionality. How many conferences can we create in freeswitch?and how to control the Creation of number of conferences in freeswitch? thanks in advance
