3cx with SBC

[Anees Cloete]

Good Day,
Please can someone clarify the use or need of the 3CX SBC.
I have a hosted 3CX PBX on OVH, I will only connect to one site with 120 users with IP phones.
Would I need SBC and if so how many?
Thanks

You could use VPN, but STUN would not be recommended, SBC would be a second choice. With that many phones, you probably won't be going with the Raspberry Pi, unless you use multiples. Have a read through these...

Thanks for the reply and links @leejor, if I read correctly I will have to then go with the vpn option as it will save me time and by the looks of things not too complicated to setup and we running pfSense as well so this helps. Thanks once again.

This was answered in your previous thread:

I agree with the previous posts - VPN for this many extensions, or if you have MPLS/VPLS infrastructure this between sites this offers the same sort of thing.

You can use Multiple SBC's on a remote site and 3CX have suggested in previous thread that this is a supported setup although personally I think that this sort of setup maybe a bit clunky and you may have to split subnets between the SBCs.
