Hi Can I use the SPA400 without the SPA9000 with 3CX? To connect our anologue non ip phones? All I want to do is connect the SPA400 to our ethernet switch, plug in 4 phones (BT V8s) and configure the SPA400 to connect to the 3CX and have our users use the phones as normal ie receive and make and transfer calls. Hence why I need the FXO gateway rather than the cheaper FXS gateways. Is this correct or am I barking up the wrong tree? All ideas are gratefully received and thank you for your help.
