Please note that the 3CX SBC is only intended for provisioning desk phones, ATAs, and FXS gateways.

GSM gateways should not be placed behind the 3CX SBC. Please refer to this document for guidance. Since GSM gateways are an unsupported setup in this configuration, any further assistance will need to be handled directly with the vendor.

Best regards,
