Zone Configuration: Advanced Settings - Cisco TelePresence Administrator's Manual

Field Description
Type The nature of the specified zone, in relation to the
local VCS. Select DNS.
Hop count The hop count is the number of times a request will be
forwarded to a neighbor gatekeeper or proxy (see the
Hop counts section for more information). This field
specifies the hop count to use when sending a search
request to this particular zone.
H.323 Determines whether H.323 calls are allowed to
mode systems and endpoints located using DNS lookups
via this zone.
SIP mode Determines whether SIP calls are allowed to systems
and endpoints located using DNS lookups via this
zone.
TLS verify Controls whether the VCS performs X.509 certificate
mode and checking against the destination system server
subject returned by the DNS lookup.
name
If TLS verify mode is enabled, a TLS verify subject
name must be specified. This is the certificate
holder's name to look for in the destination system
server's X.509 certificate.
TLS verify The certificate holder's name to look for in the
subject destination system server's X.509 certificate (must be
name in either the Subject Common Name or the Subject
Alternative Name attributes).
Media Controls the media encryption policy applied by the
encryption VCS for SIP calls (including interworked calls) to the
mode internet.
Zone Determines how the zone's advanced settings are
profile configured.
Default: uses the factory default profile.
Custom: allows you to configure each setting
individually.
Alternatively choose one of the preconfigured
profiles to automatically use the appropriate settings
required for connections to that type of system.

Zone configuration: advanced settings

The table below describes the Advanced and Custom zone configuration options. Some of these settings
only apply to specific zone types.
Note: you should only use the Custom zone profile settings on the advice of Cisco customer support.

Zones and neighbors
Usage tips
After a zone has been created, the Type
cannot be changed.
If the search request was received from
another zone and already has a hop count
assigned, the lower of the two values is
used.
This setting only applies if the DNS lookup
specifies TLS as the required protocol. If
TLS is not required then the setting is
ignored. See TLS certificate verification of
neighbor systems for more information.
See Media encryption policy
information.
See Zone configuration: advanced settings
for details on the Advanced settings.
Do not use the Custom option or configure
the individual Advanced settings except on
the advice of Cisco customer support.
