We have patton gateway SN4114/JO/EUI and would like to configure it with 3cx. We have total 4 line with 3 Phone numbers (Means one line is a chnnel/additional line of one number). I want to configure the one main line and one channel line to one specific set of ring group and other lines need configure other specific set of ring group. How I can accomplish this? Is there any document/vedio tutorial for understand more about Patton gateways incase we need to troubleshoot anything.
