Hi You may reccall I asked for help getting a spa400 to connect to our 3CX PBX. However, that failed. I have returned the item and I am looking at buying another 'gadget' that is both compatible and supported by 3CX. Before I do that, I need your advice. We cannot afford Pattons, we are a very small start up that is looking to make cheap calls and have almost zero costs on PBX etc. 3CX fits that bill perfectly. We also do not have the luxury of buying IP phones because we have already purchased BT V8's. So what I want to do is this. We have 4 phones, 1 fax, 1 line, 1 broadband. We will be moving to BT's VOIP offer which we can input into 3CX. What we want to do is connect the 4 analogue phones to 3CX using a gateway. The actual phone line is used for FAX and for broadband. No line connects with 3CX and hence we do not expect our gateway to be connected to the phone line. It will be connected to the network using a linksys switch. Our broadband will also be with BT. Please explain the FXS, FXO confusion and which one do I need to do the above. I am sure you have gathered that we need the cheapest but best solution. A grandstream for example, but which one? Apologies for the long post. and thanks in advance (TIA) for your help.
