GRUU (Globally Routable User Agent URI) support

The VCS has implemented the Public GRUU element of RFC 5627: Obtaining and Using Globally Routable User Agent
URIs (GRUUs) in the Session Initiation Protocol (SIP).

A GRUU is a SIP URI that can be used anywhere on the internet to route a request to a specific AOR instance. Note
that the registering domain must be globally routable in order for the VCS to support GRUU.

Improved DNS subsystem

The DNS subsystem within the VCS has been re-structured and improved to be standards compliant. It provides the
ability to specify explicit upstream DNS servers for specified domains.

Improved NTP synchronization

The VCS can now be configured to connect to up to 5 standards-based NTP server addresses.

TMS Agent database credentials included within local authentication database lookups

In addition to any manually created entries, the Cisco VCS now checks credentials stored within the TMS Agent
database when the device authentication database type is set to Local database.

This makes it easier to enable authentication on the Cisco VCS when provisioning is using passwords originating from
TMS.

Other enhancements and usability improvements

■

You can now configure up to 200 SIP domains.

■

You can now configure up to 10,000 local authentication database credentials.

■

Full support of RFC 5806: any SIP diversion headers received in a 302 response are now maintained in the
outgoing INVITE message.

■

Improved zone status reporting: the zones summary page now shows separate SIP and H.323 connection
status information.

■

Table sorting indicators: tabular displays now indicate by which column each table is sorted.

■

A filter facility has been added to the Subzones list page.

■

Chrome web browser is now supported; Internet Explorer 6 is no longer officially supported.

■

The administrator no longer has to log out and log back in again after reconfiguring DNS server addresses.

■

There is a new Call signaling routed mode advanced zone profile setting for neighbor zones. It controls
whether the zone always takes the signaling or uses the system-wide Call routed mode setting.

■

There is a new H.323 call signaling port advanced zone profile setting for neighbor zones. It identifies the call
signaling port on the neighbor system to use if Automatically respond to H.323 searches is set to On.

■

SSH and SCP clients are no longer available in the VCS operating system.

■

Reverse Path Filtering (RFC1812) is enabled by default. This ensures that the VCS will only accept packets on
interfaces from source addresses to which there are valid routes in the routing table for that interface. This
change may necessitate the adding of additional static routes on dual-interface VCSs to ensure the VCS
routing table matches the network topology.
