These phones are especially suitable for use with phone systems (PBX's), but can also be used alone.
Most phones listed here, including Fanvil, Yealink and Snom, have Zero Touch provisioning/setup, which means that they can be automatically provisioned from phone systems that support this. The phones can thus be sent directly to a user without having to go through the IT department first. The user just connects the phone, enters a PIN code and the phone is set up automatically.
Technically, this works by the phone's unique MAC address having been entered in advance by the IT department in the PBX/provisioning server. This makes mass rollout and administration of phones extremely easy and thus provides optimal user experiences and great savings.
