Zones
Configuring zones
Common zone configuration options
The zone configuration options depend upon the zone Type,
however the following options apply to every zone type:
Name
The name acts as a unique identifier, allowing you to distinguish
between zones of the same type.
Type
The nature of the specified zone, in relation to the local VCS:
Neighbor: a connection to a neighbor system of the local VCS.
Traversal client: the local VCS is a traversal client of the system
being connected to, and there is a firewall between the two.
Traversal server: the local VCS is a traversal server for the
system being connected to, and there is a firewall between the
two.
ENUM: the zone contains endpoints discoverable by ENUM
lookup.
DNS: the zone contains endpoints discoverable by DNS lookup.
After a zone has been created, the Type cannot be changed.
Hop count
The hop count is the number of times a request will be
forwarded to a neighbor gatekeeper or proxy (see the
section for more information). This field specifies the hop count
to use when sending a search request to this particular zone. If
the search request was received from another zone and already
has a hop count assigned, the lower of the two values is used.
After creating a zone you must make it a target of at
least one of your zone policy search rules. If the zone is
not included as a target in your search rules, search
requests will not be sent to that zone. See the
search and zone transform rules
section for more information.
The sections that follow describe the specific additional
configuration options that apply to each zone Type.

The following options are available (in addition to the Name, Type
and Hop count described in the
configuring a neighbor zone on the VCS. Neighbor zones are used
to enable a connection from the local VCS to a neighbor system.
Systems that are configured as cluster peers (formerly
!
known as Alternates) must not be configured as
neighbors to each other.
H.323
Mode
Determines whether H.323 calls are allowed to and from the
neighbor system.
Port
Specifies the port on the neighbor system used for H.323 calls
from the local VCS.
This must be the same port number as that configured on
the neighbor system as its H.323 UDP port. If the neighbor is
another VCS, this is the port found under the VCS configuration
> Protocols > H.323 in the Registration UDP Port field.
SIP
Mode
Determines whether SIP calls are allowed to and from the
Hop counts
neighbor system.
Port
Specifies the port on the neighbor system used for SIP
connections from the local VCS.
This must be the same port number as that configured on the
neighbor system as its SIP TCP, SIP TLS or SIP UDP listening port
(depending on which SIP transport mode is in use).
Configuring
Transport
Determines which transport type is used for SIP calls to and from
the neighbor system.
The default is TLS.

TLS verify mode
Controls whether the VCS performs X.509 certificate checking
against the neighbor system when communicating over TLS.
If the neighbor system is another VCS, both systems can verify
each other's certificate (known as mutual authentication).
See
TLS certificate verification of neighbor systems
information.
Authentication trust mode
Controls whether authenticated SIP messages (ones containing
a P-Asserted-Identity header) from this zone are trusted without
further challenge.
See
SIP authentication trust
for more information.
Accept proxied registrations
Controls whether proxied SIP registrations routed through this
zone are accepted.
This setting only applies to registration requests for a domain
for which the VCS is acting as a Registrar. For requests for other
domains the SIP Registration Proxy Mode setting applies.
See
Proxying registration requests
for more information.
Location
Peer 1 to Peer 6 address
The IP address or FQDN of the neighbor system. If the neighbor
is a VCS cluster, this includes all of the peers in the cluster. See
the
Neighboring the local VCS to another VCS cluster
more information.

Zone configuration: advanced settings
