Provisioning
Phones can be provisioned to download configuration profiles or updated
firmware from a remote server when they are connected to a network, when they
are powered up, and at set intervals. Provisioning is typically part of high-volume,
Voice-over-IP (VoIP) deployments and limited to service providers. Configuration
profiles or updated firmware are transferred to the device by using TFTP, HTTP, or
HTTPS.
The Cisco IP phones accept configuration profiles in XML format, or in a
proprietary binary format generated by the SIP Profile Compiler (SPC) available
from Cisco. The Cisco IP phones support 256-bit symmetric key encryption to
secure the XML content of the profiles. SPC compiled binary profiles can be
encrypted when they are complied. Since firmware does not contain sensitive
personal information, typically it is not encrypted.
Provisioning is described in detail in the
Cisco Small Business IP Telephony
