I had 3 concurrent calls (without recoding) many times. On my testing RPi the CPU usage was only around 5% per call, so I can imagine a lot more concurrent calls are possible.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I can get usually upto about 9-11 calls without voice degradation (no transcoding ONLY u711). The cpu and memory are still low but regardless of this voice quality starts to break down around the 10 concurrent call mark. I think this is pretty INCREDIBLE for a U$35 dollar credit card sized pc. Definitely it can handle any home and LOTS of small business.
I also noticed that there isn't a 100% direct relationship between cpu/memory/load and voice quality. If I get 20 concurrent calls going the cpu/memory doesnt go up so high but the voice quality is terrible!
I put a pic of the cpu/mem etc just as a reference.
ps... all calls are recorded so this for sure affects the numbers...
If I can I'll try to disable the recordings and repeat the tests...
hi, guys :)
amount of concurrent calls that support this version of asterisk?
we're working on it.

Toping is old. But how what sort of calls ist that? VoIP calls I guess?
How many devices (surfsticks) can be used?
Somebody knows how many concurrent calls support the new Raspberry Pi 3
@jorge Great question. Any update ?
