Please, help me with this problem. I have 3CX Free Edition, 3 extensions (PC, Ip phone, D-Link FXS gateway). I also have D-Link DVG-3004S FXO gateway with 4 ports. I'm setting up 1 FXO port, connecting it to office line, creating a PSTN in 3CX, setting up rules. Everything works well. When i'm doing so with next FXO port and second line - nothing occurs. In gateway status port shown as registered and ready, but when i'm placing a call thru this line (line->FXO), there is no effect, looks like the phone cable is not connected to gateway. Whats up? Thank you.
