System requirements?

[el_dorado]

Hi! I want to have 20 concurrent calls to Yate IVR autoresponder (on the same machine), via 2G YateBTS. Please recommend me the setup:
- OS (which Linux distro is better)
- CPU
- Memory

All I find were articles about Raspberry Pi 3 B. Will Raspberry Pi be good for my task? Which max calls + IVR Raspberry Pi can handle?

Radio is bladeRF x40.

Hi,

You need to configure multiple arfcns in yatebts. By default you can only have:
* Call capacity:   7 concurrent full rate call

YateBTS doesn't support half rate, so you can't increase call capacity this way. From yate's point of view 20 ivrs aren't a big number, but running multiple arfcns takes more resources and decreases coverage. In the end you'll need to experiment. Let us know how it goes.

Good luck

Thank you. It seems, I should try.

USB 2.0 interface can't handle much concurrent calls, maybe several, I have not tested a lot.

Dual-core CPU can handle up to 20 concurrent calls, but all is limited to USB throughput.
