Definition
A type of DNS record that maps a host name to an IPv4 address.
A type of DNS record that maps a host name to an IPv6 address.
See Call Policy
The name an endpoint uses when registering with the VCS. Other endpoints
can then use this name to call it. An endpoint may register with more than
one alias.
One or more VCSs configured to support the same zone in order to provide
redundancy. See also Cluster.
A SIP or SIPS URI that points to a domain with a location service that can
map the URI to another URI where the user might be available. Typically, the
location service is populated through registrations. An AOR is frequently
thought of as the "public address" of the user.
An endpoint RAS request to make or answer a call.
Cisco's proprietary protocol for firewall traversal.
A device used to control multimedia networks and firewall traversal.
An organization that validates and signs certificate requests.
A CAC is a smart card (or similar) device that contains a user's unique
certificate and private key. Access to the certificate and key is granted by
entering a PIN code and the certificate is used in mutual authentication with
other systems to prove the identity of the user. This is classed as two-factor
authentication as the user needs both the CAC and the PIN to access its
contents.
In relation to the VCS, the set of rules configured system-wide (either via the
web interface or CPL script) that determine the action(s) to be applied to calls
matching a given criteria. (Also referred to as Administrator Policy.)
A Cisco product used for the management of video networks.
A generic term for the Cisco product which acts as a gatekeeper and SIP
proxy/server.
A VCS whose main function is to act as a gatekeeper, SIP proxy and firewall
traversal client. This system is generally located within the firewall.
