Unfortunately, you can't use the 286 to connect 3CX to a PSTN line. The 286 is used to connect a telephone set to an IP server (FXS). For a PSTN line you will need a gateway (FXO). Grandstream makes a number of them. One of the more flexible is the Linksys/Cisco SPA3102. It contains both an FXO and an FXS in one device. This allows you bring one phone line into 3CX as a trunk, and also allows one regular telephone to act as an extension on the PBX.
