Which RPi for SBC

[Lee Cramman]

I need to deploy a small, temporary site that will be in place for about 6 weeks and I want to use an SBC to keep things as easy to configure as possible on the networking side.

There will only be about a dozen end points so I was thinking a Pi would be the way to go but I've never used a Pi for this before. Also, there is the possibility that I may have to deploy something more permanent for about 30-40 end points on this site at a later date. The site will be very light users of BLF.

Is there any recommendation as to what the best RPi model to use would be and, if the site does become permanent and expand to 40 end points later on, will the Pi still be able to handle it or should I go for a full fat PC / server / VM?

Rpi 3B+ is good enough and robust, i use several with no problems.

you need to buy a good power supply, a good and fast 32Gb SD card

As always, you need a good internet connection to have enough bandwith

Follow V16 install steps from 3CX docs, once online you surely forgot it, it works fine

Hello @Lee Cramman !

3CX recommend to use a Raspberry Pi 3B+and it will be 20 extensions and 10BLF/ext

For something like 40 extensions you'll probably need another support !

Get yourself 2 Pis and have them over 2. Better to have too much then too little.

Latest SBC running on Pi 3B+ should be able to handle 40 phones and 600 BLF

Awesome, thanks guys. 40 is an absolute max and we're only looking at a handful of BLF's so the 3B+ sounds ideal.

I'll probably just buy 2 to have a warm spare to drop in 'just in case'.

We do use the RPi for other stuff and I have a preference for hanging them off suitably spec'd USB power bank w/ adaptor to act as a poor man's UPS.
