I bought a Patton SmartNode SN4114 VoIP media gateway with 4 FXS and FXO Ports. I want to use it to receive and make calls on my Analog PSTN line. I followed the 3CX guide and tried the following but none seem to work. First method I tried is as follows: * Went to Add Gateway and gave it a name * Selected brand as Patton * Then for Model there doesnt seem to be much options only Analog FXO, FXS 2 port, and FXS 4 port. So I selected Analog FXO. * Then next step I selected Country as UK, defined ports as 4 (even though I'm only using 1 line, but according to guide it's the amount of ports the device has) * Dial delay left as Wait for Dial Tone * Mode left as Normal then pressed next * Next Set the IP address of the SN4114 and pressed next * In the next step it says to set channels and I set it to 1 as detected by default. * Next the Outbound rules I left everything blank and put route 1 as Patton device with strip 0 digits. * Then I generated the config file and loaded it onto the SN4114 and pressed reload on the SN4114. * After the device came back up, I tried to make outbound call and it just doesnt work. I keep getting Busy tone. So I thought maybe it's not FXO and FXS that I have to add, so deleted it and started over to add the Gateway again. But this time as the model I selected Patton 4 Port FXS. Problem is that when I select this, it asks me to map extensions to the 4 ports. So not sure what i'm supposed to do there as I do not really want to assigned the port to an extension.
