Zone matches replaced by search rules
Instead of specifying up to 5 matches when configuring a zone, you now set up separate search rules and
associate each rule with a target zone to where the query is forwarded.
You can configure up to 2000 search rules.
n
A Stop searching option makes the search process more efficient by allowing you to stop searching any
n
further zones when a search rule results in a successful match.
A Source option lets you control whether a search rule is applied depending on the source of the query.
n
The Calls to unknown IP addresses and Fallback alias configuration settings have moved from the
n
Calls page to a new Search rules configuration
Quality of Service
The VCS supports the DiffServ (Differentiated Services) Quality of Service mechanism for tagging all
signaling and media packets flowing through the VCS over IPv4 and IPv6 protocols.
Expressway call licensing
A non-traversal call on a VCS Expressway now consumes a traversal license if there are no non-traversal
call licenses available.
Microsoft Office Communications Server 2007 integration
The OCS Relay application is now supported in a VCS cluster and with an OCS cluster.
n
OCS Director is now supported.
n
TURN server
A VCS Expressway can act as a standards-based TURN server, allowing ICE-enabled endpoints to traverse
NAT firewall devices.
TURN services do not consume traversal call licenses but instead you need to install the TURN Relay
n
option key which controls the number of TURN relays that can be simultaneously allocated by the VCS.
This replaces the STUN Relays used in version X4 (which consumed traversal call licenses).
n
CPL
The rule node supports a message-regex parameter that allows a regular expression to be matched
against an incoming SIP message. Note that this parameter does not apply to H.323 calls.
VCS warnings display as TMS trouble tickets
Warnings raised on the VCS are also raised as TMS tickets.
Call media statistics
Improved media statistics can be viewed on the
counters are now per call rather than per socket
n
lost, duplicate and out of order packet counts
n
jitter on each RTP channel in a call
