Provisioning; Redundant Provisioning Servers - Cisco 8831 Administration Manual

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 conference phone accepts configuration profiles in XML format, or in a proprietary binary format
generated by the SIP Profile Compiler (SPC) available from Cisco. The conference phone supports
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 Unified IP Conference Phone 8831 for Third-Party Call
Control Provisioning Guide.

Redundant Provisioning Servers

The provisioning server may be specified as an IP address or as a fully qualified domain name (FQDN).
The use of a FQDN facilitates the deployment of redundant provisioning servers. When the provisioning
server is identified through a FQDN, the Cisco IP phone attempts to resolve the FQDN to an IP address
through DNS. Only DNS A-records are supported for provisioning; DNS SRV address resolution is not
available for provisioning. The Cisco conference phone continues to process A-records until the first
server responds. If no server associated with the A-records responds, the Cisco Unified IP Conference
Phone 8831 for Third-Party Call Control logs an error to the syslog server.
