Advanced → QoS/Security → Security → SBC config file URL
The URL of the 3CX SBC tunnel configuration.
This setting is only working after the 3CX SBC feature update is installed on the phone and the setting prov_3cxsbc_enabled is set to on. After the URL is set, the phone needs to reboot to fetch the configuration file on startup. After the configuration file is fetched, the setting is cleared and the phone will reboot. On the next startup the phone will start the 3CX SBC tunnel automatically.
This setting is only available on D8XX phones.
Valid URL to a plain 3CX SBC configuration file.
