Hello, I have one simple question: Is there any way to setup a Sangoma card (specificaly the model A200-A20002)for 3CX? Thanks in advance. I already have a GXW4104 but as long as nobody could help me: from 3CX let me waiting, even the support team from Grandtream never answered. And at the support page 3CX changed the recomended to supported so I guess is a real trash what I bought. Even at the forum people says very bad things about this FXO so I guess it is a bad gateway. Too late to know it but still I have to fix the problem. Thanks in advance.
