Hi I have been using 3CX for the last 4 years but have increasingly experienced connection problems either from VOIP provider or wider internet issues. The decision has therefore been made to move away from our broadband connection and migrate to using ISDN lines via a VOIP gateway. Wishing to restrict choices to 3CX approved gateways it appears we have a choice between Beronet Berofix 400 (4BRI) or say a Patton smartnode 4120/4634. I have searched forums and there is very little mention of these devices. Is this because they generally install, configure and work reliably? Or is it because those of you who are experts in these matters know to steer clear and avoid problems? My question is therefore has anyone good, or bad, experiences of using these devices in the UK. Thank in advice for any feedback.
