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

Zones and neighbors
Field Description
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).
Fallback The transport type to use for SIP calls from the DNS
transport zone, when DNS NAPTR records and SIP URI
protocol parameters do not provide the preferred transport
information.
The default is UDP (if enabled).
Media Controls the media encryption policy applied by the
encryption VCS for SIP calls (including interworked calls) to the
mode internet.
ICE Controls whether ICE messages are supported by
support the devices in this zone.
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.

Zone configuration: advanced settings

The table below describes the advanced zone configuration options for the Custom zone profile. Some of
these settings only apply to specific zone types.
Setting Description
Monitor peer Specifies whether the VCS monitors the status of the zone's peers. If
status enabled, H.323 LRQs and/or SIP OPTIONS are periodically sent to the
peers. If a peer fails to respond, that peer is marked as inactive. If all peers
fail to respond the zone is marked as inactive.
Call signaling Specifies how the VCS handles the signaling for calls to and from this
routed mode neighbor.
Auto: signaling is taken as determined by the Call signaling optimization
(Configuration > Call
Always: signaling is always taken for calls to or from this neighbor,
regardless of the Call signaling optimization configuration.
Calls via traversal zones or the B2BUA always take the signaling.

routing) configuration.
Usage tips
This setting only applies if the DNS lookup
specifies TLS as the required protocol. If TLS
is not required then the setting is ignored.
