Zones
Configuring neighbor 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 th
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 
 section for more information.
The sections that follow describe the specific additional 
configuration options that apply to each zone Type
Configuring zones
The following options are available (in addition to the NameType 
and Hop count described in th
 section) when 
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 
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).
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).
Se
 for more 
information.
Authentication trust mode
Controls whether authenticated SIP messages (ones containing 
a P-Asserted-Identity header) from this zone are trusted without 
further challenge. 
Se
 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.
Se
 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 
 
section for more information.
Advanced
See the 
 section 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.
