Hi! I am completely new to 3CX (and VOIP) and trying to evaluate it to replace an existing Panasonic system. I consider our installation to be quite small, but when I look at the configuration instructions for the recommend VOIP gateways, I start to wonder. They all seem to be quite low capacity (4 or 8 port) and none of them are for T1 connections. We have about 70 extensions and about 20 active channels on a T1 line to the telephone company. Is 3CX able to handle a system of this size easily and grow significantly beyond it? Are people currently running larger systems? Have people interfaced it to T1 PRI gateways and if so, are there instructions available? regards, Alan.
