3CX SBC for another 100 extensions

[Ruymar Castro]

Guys, I would like to clear a doubt, what is advised by 3CX to use Gateway'S FXS (over 100 extensions, my project is 480 TDM extensions), regarding the SBC?
Does 3CX have SBC for registration over 100 extensions? In a case like this I have to register 480 TDM extensions how to do with SBC?

You can have multiple SBCs, at one location, as needs require.

The recommended (but not mandatory) number for each SBC is 100 users, with appropriate hardware: https://www.3cx.com/docs/recommended-hardware-specifications-for-3cx/
I think you can use more than one SBC (for example one for each floor). Or use more performing hardware.

But can I use more than recommended? Example I can put a hardware with more processing and more memory and increase the amount of extensions

Recommendations are usually there for a reason.
You certainly could try. If it didn't work, you'd have to add a second SBC. Whether you have issues at some point will probably be determined by what functions the sets are having to perform, and the processor and memory requirements of those functions. There may also be some limitation, determined by the software that 3CX would have to comment on
.
I'm not certain that anyone has kept loading a high power SBC until the "breaking" point. Perhaps you can be the first and let us know how it goes.

Personally, I would want to distribute sets across a number of lower power (less expensive) SBCs, rather than have a single point of failure.
