Pi 4 for 12 extensions

[New_Frontier]

I've currently got a customer who needs 12 extensions. Fewer than eight simultaneous calls, and many of the calls will be internal. At max 2-3 external calls simultaneous, but even that much traffic is likely infrequent.

What I'm trying to determine is if a Raspberry Pi 4 will be sufficient to handle the volume. My gut says yes, but I know there's a lot of people on here FAR more experienced who could hopefully give me their two cents.

According to this you should be absolutely fine.

I once put in a Pi 3B+ with about 6 extensions with call recording enabled and about 3 BLFs per phone with no issues.

With a Pi 4 you'll get even more power so as long as you limit your BLFs i think you'll be fine.

Appreciate the info and the link. I'd not yet seen that page. Six of the phones will have about 15 BLFs each, and six will only have 2 or 3. While the info in the attached document isn't clear on BLFs for a PBX (it only discusses them for an SBC), it looks like I'll probably be ok with the Pi4 B8.

Thanks again for the response.

Hi @Battery111,

For the number of BLFs you're talking about above, the Pi4 B8 should do the trick without a problem.

Just to report back. The Pi seems to be handling everything just fine. I appreciate the insight from those more experienced than myself.

I will admit I'm a bit unhappy with the 3CX standard template for the X4U. I understand that six pages of BLF gives you more options, but when the customer only wants 15 BLF and they're on page two needing a button on page one, they don't want to go through three extra pages to get there.

I found the thread on creating a custom template to fix this, but the real solution seems fairly obvious. Allow the number of pages to be configured from the provisioning tab.

Hi @Battery111,

For the Fanvil X4U issue, I'd suggest opening a new thread in the IP Phones section.
