First a dislcaimer: Im new to 3cx and VOIP overall so I may overlook simple things. Thank you in advance for all help. Tomorrow Ill be setting up my 3cx system for use on a T1 gateway. Ill be using a Sangoma 102 t1 card. I know that I need to set up a gateway rule via the PSTN tab on the 3cx phone system. So I have a VOIP provider set up but I assume that is what I wont be using for the T1 as my company has a voip gateway set up. Is this correct? What things should I pay attention for? What are some common mistakes that happen when setting this up? Any links you guys recommend? Any and all advice is welcome. Thank you!
