SIP session expiry timers can be configured through the Session refresh interval and Minimum session
n
refresh interval settings.
SIP device interoperability can now be configured through the Require UDP BFCP mode and Require
n
Duo Video mode settings. Note that the default setting of On for these modes is not supported by some
neighbor systems so make sure you select the appropriate Zone profile when configuring zones.
X4
Multiway™
VCS now supports standards-based Multiway™. This feature allows endpoint users to initiate ad hoc
multiparty calls from their endpoint, -even if the endpoint does not have embedded MultiSite™ capabilities.
To enable this feature you must enable and configure the Conference Factory application on the VCS.
TMS Agent
The TMS Agent allows Movi™ v2.0 clients registered to the VCS to be provisioned with phone book and
configuration information by connecting to the VCS rather than directly to TMS.
Microsoft OCS 2007 interoperability
The VCS now includes an OCS Relay application, which makes FindMe presence information available to
n
Microsoft Office Communicator (MOC) clients, and enables Microsoft Office Communications Server
(OCS) 2007 to forward calls to FindMe aliases.
Neighbor and DNS zones now include a pre-configured zone profile for connections to an OCS.
n
Static NAT support
A VCS Expressway with the Dual Network Interfaces option installed can now be deployed in a DMZ with a
static private address mapped to a public IP address of the external firewall.
Password security
You can determine whether or not administrator passwords must meet a minimum level of complexity
n
before they are accepted.
The admin administrator account and the root account can now have separate passwords.
n
A warning will appear if the password of the default admin administrator account or the root account are still
n
set to the default.
Root account access
Access to the root account using Telnet and SSH can be disabled to increase security on the VCS (access
over Telnet is now disabled by default).
Capacity warnings
The VCS can now raise a warning when it is approaching its maximum licensed capacity for calls or
registrations. This feature is managed using the CLI only using the command: ResourceUsage Warning
Activation Level: <0..100>
Clustering
The replication of configuration information (including FindMe information) no longer requires the use of TMS.
Information is replicated across the peers in a cluster within 60 seconds.
