Hi We have a few BT V8s and was hoping someone here can help me. Which gateway should I get. I have seen the list on 3CX website which says that we can use the following Grandstreams: Grandstream GXW-4024/4004 FXS GrandStream GXW-4104 / 4108 We have just started our business and our office is in the UK, currently we only have an ordinary BT line and a 3CX server. Our USB phones work OK but have found certain limitations and would like to upgrade and use the V8s we have already. From the little I have read, I believe we can connect our V8's to the above gateways and upon the relevant settings on the Gateways voila we will have a working set of phones :-}. We would be very grateful for your advice. Thank you.
