3CX SBC on Raspberry Pi

[Anotherusername]

Hi all,

I can't seem to find any hardware requirements for running an SBC on a Raspberry Pi.

https://www.3cx.com/docs/recommended-hardware-specifications-for-3cx/ only mentions hardware requirements for Intel. Does anyone have a list of Rasberry pi models and how many users would be feasible to connect?

See https://www.3cx.com/docs/installing-pbx-raspberry-pi/
re: devices, it wasn't a huge number but I don't remember what it was exactly. We have a site with ~15 phones I can think of offhand and it wasn't a concern. I suspect since 3CX now supports using a phone for an SBC the goal is move away from Pis (?).

Yeah that's true but the limit on using phones as SBC is 10 and I read somewhere that a raspberry could do up to 50 but I'd like a more reliable source for this before comitting to buying one for testing.

Hi,
The hardware specs page used to have the details for using RPi for PBX or SBC but as they are hard to find now, plus with the Router Phones the details appears to have been removed.

Here's the details courtesy of web archive:

Raspberry Pi 4 (B4 or B8) as 3CX SBC
Extensions up to 50 (10 BLFs per device)
SIM Calls (SC) up to 64
SD Card minimum 32GB Class 10 Micro SD
Required Heat sink housing and Raspberry Pi-compatible 2.5 Amp Micro USB power supply.

3CX PBX is no longer supported on Raspberry Pi devices
