• Retail distribution—The customer purchases the Cisco IP Phone from a retail outlet and requests VoIP
service from the service provider. The service provider must then support the secure remote configuration
of the device.
Bulk Distribution
In this model, the service provider issues phones to its customers as part of a VoIP service contract. The
devices are either RC units or preprovisioned in-house.
Cisco preprovisions RC units to resynchronize with a Cisco server that downloads the device profile and
firmware updates.
A service provider can preprovision phones with the desired parameters, including the parameters that control
resynchronization, through various methods:
•
In-house by using DHCP and TFTP
•
Remotely by using TFTP, HTTP, or HTTPS
•
A combination of in-house and remote provisioning
