Hi, We're looking at using 3cx for an academy trust of schools. We have the current setup: Server hosted at one school with direct extensions (50) A few extensions at some offices using an RPi as an SBC A second school is about to go live with 35 extensions and an SBC on a VM We're looking at going cloud hosted with the server and adding at least one more school in. This new school has nearly 100 extensions, so one SBC won't cut it. Could we use two SBCs on the same network? We have four learning communities of schools, so what is the optimum setup? One server per community with bridges, or one cloud server (cheapest option) and SBCs? We'd rather not have to maintain multiple servers if possible, but can see the benefit with bridges should one server fail, the other communities can still function.
