SBC Sizing

[GMCS]

Good day,

I have a client that has about 8 phones (Fanvil) that have about 15 or so BLF keys setup. They are currently on STUN and need to switch them over to a SBC when I upgrade to V20. I usually use Raspberry Pi's for all my cliends, but I read their is a limitation of devices, and BLF per device. I know i can use a few Router phones as SBC's but i would like to try to limit the purchas of equipment if possible. What would be my best choice for this, in total 8 Fanvil phones with about 15 BLF each (120BLF Total), 2 Yealink basestations, that each have about 6 extensions/handsets. And I also have about 12 Grandstream IP PA Speakers.

Thanks!

For the router phones you can have up to 10 devices provisioned behind one router phone. This is also clarified here.
However for the BLF keys it is suggested to keep the 10 BLF keys per device.
In your case if all 8 Fanvil are router phones then use them all as SBC's and split all others.

Given the price / availability of RasPis these days, a PC or a VM are more performant for similar money.
