Hello, I have used the Patton Excel sheet macro to create a configuration file for my SN-4114 device. Now, how do I proceed to set up 3CX phone system to use it? Create a generic gateway? My SN-4114 has 2 FXS ports (fax machines) and 2 FXO ports (PSTN phone lines for outgoing/incoming calls). Your help is very much appreciated.
