Enhanced authentication policy
Authentication policy can now be applied at the zone and subzone levels. It controls how the VCS
authenticates incoming messages from that zone or subzone and whether those messages are
rejected or are subsequently treated as authenticated or unauthenticated within the VCS.
authenticates incoming messages from that zone or subzone and whether those messages are
rejected or are subsequently treated as authenticated or unauthenticated within the VCS.
This provides increased flexibility and allows system administrators to:
n
control registrations via subzones; this allows, if required, a combination of authenticated and
unauthenticated endpoints to register to the same VCS
unauthenticated endpoints to register to the same VCS
n
limit the services available to unregistered or unauthenticated endpoints and devices
n
cater for endpoints from third-party suppliers that do not support authentication within their
registration mechanism through a "treat as authenticated" setting

External policy services
The VCS can be configured to use external policy services to manage its registration and call policies.
This is particularly suitable for large-scale deployments where policy decisions can be managed
through an external, centralized service rather than by configuring policy rules on the VCS itself.

Secure communication between cluster peers
The VCS uses IPsec (Internet Protocol Security) to enable secure communication between each
cluster peer. Authentication is carried out through the use of a pre-shared access key (configured on
the Clustering page).

View registrations and calls across a cluster
You can now view all of the registrations and calls across a cluster from any one of the peers in the
cluster. A Peer column on the registrations and calls status pages identifies the relevant peer.

Client-initiated connection management
The VCS has implemented support for RFC 5626 (known as "SIP Outbound"). This allows a UA to
route calls when a peer in a cluster has failed, and also allows a UA to close all listening ports ensuring
all calls can only be routed via their existing (authenticated, authorized) connection to the VCS.

Starter Pack enhancements
n
The VCS Starter Pack Express supports device provisioning for E20 and Ex series endpoints.
n
Additional call license option keys can be added to extend the default limit of 5 concurrent calls.
User interface language packs
Multiple language support has been enabled on the VCS's web interface. Language packs will be
made available for download in the future. Contact your Cisco support representative for more
information on supported languages.
