X5.1 - Cisco TelePresence Administrator's Manual

Encrypted calls to and from Microsoft OCS Server 2007 for both native SIP calls and calls interworked from
H323 are now supported. This feature is enabled by the Enhanced OCS Collaboration option key. Note
that as the VCS must process the media in both scenarios, a traversal call license is used.
Message waiting indication
The VCS now supports forwarding of unsolicited NOTIFY messages to registered endpoints. This allows
message waiting indication from CUCM to be forwarded to E20s thus allowing the indicator light to flash.
Ports
The VCS no longer listens on multicast/port 1718 when H.323 Gatekeeper Auto discover mode is set to
Off (this has the effect of disabling IGMP messages).
Call bandwidth
The maximum value for the default call bandwidth on a VCS has been increased from 2048 kbps to 65535
kbps.
Presence
Default timers for the Presence User Agent retry attempts have been increased to prevent resources being
consumed.
The default Subscription expiration time has increased from 300 to 3600 seconds.
n
The default Publication expiration time has increased from 120 to 1800 seconds.
n
The default PUA resend time (not configurable through the web interface) has increased from 5 to 1800
n
seconds.

Usability enhancements
Description fields for configuration items: a free-format description can be specified for the following
n
configuration items: transforms, Allow List and Deny List patterns, search rules, subzone membership
rules. When viewing the summary list of these items the description is displayed as a mouse-over tooltip.
Enable and disable configuration items: transforms, search rules and subzone membership rules can
n
be individually enabled and disabled. This makes it easier to make or test configuration changes.
Previously, configuration items would have to be deleted and re-created as necessary. The enabled or
disabled state is clearly shown on the summary list pages.
"Add suffix" and "add prefix" transform options: new pre-search transform pattern behavior options let
n
you add a prefix or suffix to the matching alias. Previously, regular expressions would have been required
to do this.
Consistent create and modify behavior for configuration items: for configuration where multiple items
n
can be defined (for example, Allow List patterns, search rules and so on) the create and modify behavior
has been made consistent so that you are always returned to the summary list page after saving your
changes.
Additionally, new search rules, subzone membership rules, subzones and zones are all created in a single
step. Previously you had to specify some of the configuration values when creating the item, and then
return to the edit page to specify the remainder of the values.
"Please select" in drop-down fields: when creating configuration items some of the default values
n
presented in drop-down selection fields have been replaced with a "please select" value. This helps prevent
potentially undesirable default values being selected by mistake.
