In a retail distribution model, a customer purchases a Cisco voice endpoint device,
and subsequently subscribes to a particular service. The customer first signs on to
the service and establishes a VoIP account, possibly through an online portal.
Subsequently, the customer binds the particular device to the assigned service
account.
To do so, the unprovisioned Cisco IP phone is instructed to resync with a specific
provisioning server through a resync URL command. The URL command typically
includes an account PIN number or alphanumeric code to associate the device
with the new account.
In the following example, a device at the DHCP-assigned IP address 192.168.1.102
is instructed to provision itself to the SuperVoIP service:
http://192.168.1.102/admin/resync?https://prov.supervoip.com/cisco-init/
1234abcd
In this example, 1234abcd is the PIN number of the new account. The remote
provisioning server is configured to associate the Cisco IP phone that is
performing the resync request with the new account, based on the URL and the
supplied PIN. Through this initial resync operation, the Cisco IP phone is
configured in a single step, and is automatically directed to resync thereafter to a
permanent URL on the server. For example:
https://prov.supervoip.com/cisco-init
For both initial and permanent access, the provisioning server relies on the Cisco
IP phone client certificate for authentication and supplies correct configuration
parameter values based on the associated service account.

Automatic In-House Preprovisioning
Using the web UI and issuing a resync URL is convenient for a customer in the
retail deployment model, but it is not as convenient for preprovisioning a large
number of units.
The Cisco IP phone supports a more convenient mechanism for in-house
preprovisioning. With the factory default configuration, a Cisco IP phone
automatically tries to resync to a specific file on a TFTP server, whose IP address
is offered as one of the DHCP-provided parameters. This lets a service provider
connect each new Cisco IP phone to a LAN environment configured to
