To establish connectivity between the FCM5600 and the FIBERME FGX45xx GSM Gateway Remotely , it is essential to enable the FCM5600 RFC to connect with the FIBERME FGX45xx GSM Gateway. This configuration allows the extension in the FCM5600 to integrate with a SIM card, enabling both outbound and inbound calls through the “Extension” or “Queue” via the cloud, eliminating the need for local connectivity.
