Firmware Upgrade With a Browser Command

An upgrade command entered into the browser address bar can be used to upgrade firmware on a phone.
The phone updates only when it is idle. The update is attempted automatically after the call is complete.
To upgrade the conference phone CP-8831-3PCC via URL on web browser enter this command:
http://<phone_ip>/admin/upgrade?<schema>://<serv_ip[:port]>/filepath
Configure a Custom Certificate Authority
Digital certificates can be used to authenticate network devices and users on the network. They can be
used to negotiate IPSec sessions between network nodes.
A third party uses a Certificate Authority certificate to validate and authenticate two or more nodes that
are attempting to communicate. Each node has a public and private key. The public key encrypts data.
The private key decrypts data. Because the nodes have obtained their certificates from the same source,
they are assured of their respective identities.
The device can use digital certificates provided by a third-party Certificate Authority (CA) to
authenticate IPSec connections. See the Cisco Unified IP Conference Phone 8831 for Third-Party Call
Control Provisioning Guide for more information.
The phones support a set of preloaded Root Certificate Authority embedded in the firmware:
