I have a Patton SN4114 FXS 4-port gateway. It was working fine under 3CX v14 Standard Edition (Windows). After upgrading to 3CX v15 Standard Edition (Debian 9) it is still working fine. All 4 attached phones can make and receive calls, and I see the 4 ports listed on the Phones page. However, when I look at the FXS/DECT page, there is no device listed. Should I try to add the Patton device to the FXS/DECT page? Or should I just leave it the way it is ? It seems like it is "half configured" right now. I'm just wondering if this is okay, or will it cause issues down the road? Bob B.
