Hosted and SBCs

[GoldenYears]

Hello,

We are looking at the idea of putting all of our 3CX servers in the cloud (not sure if self-hosted or hosted is the way to go, yet). Currently we have five that we manage and they are on-prem using newer-gen i5 or i7 Intel Nucs with 16GB RAM that would each be turned into an SBC should we move said servers to the cloud.

The one thing stopping us is the required use of multiple 3CX-supported Grandstream GWX4224 ATA's in each location for analog telephone connections. At the largest location we have 173 extensions, 151 of those being regular analog phones connected to the ATA's, the rest are Yealink T54W phones and they like their BLF's . Each location has 16 SC licenses.

Would an on-site SBC or two (or three?) be the correct way of going about this if it is possible? I've yet to install more than one SBC in all cases so far as noting up until now required any more that that.

The biggest consideration for SBC sizing is simultaneous calls (16 in your case) and BLF Keys (in this case not many as most phones are Analog). You should do well with 1 SBC of the above performance.

re: hosting, 3CX lists up to "large" (250 ext) at the bottom of: https://www.3cx.com/docs/recommended-hardware-specifications-for-3cx/#h.4z53dfbtxlno

SBC is listed on the same page, https://www.3cx.com/docs/recommended-hardware-specifications-for-3cx/#h.za60f8obhoix. Note it's "Up to 100 (10 BLFs per device)" so 1000 BLFs.

16 calls is not many for 173 extensions.

Note you can have multiple SBCs, and/or use High Availability: https://www.3cx.com/docs/sbc-high-availability-cluster/

Well, it doesn't seem like a lot when there is that many extensions, but we haven't hit 16 simultaneous calls yet. The 173 extensions won't have any use of BLF's because they are plain 'ol RJ11-connected analog phones.

Right, I was yes-and'ing CentrexJ.
