Dear NFON customers,
In order to make the provisioning of your end devices even more secure, we will be making two-factor telephone provisioning availableacross all NFON-certified devices in the coming weeks.
Nothing will change for end devices that are already in use. New phones or phones that are reset to factory settings will require a PIN for activation in the future. IP whitelisting is also available to simplify and accelerate provisioning.
More information can be found here.
Your NFON Team
