Field Description
Configuration section:
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. Select Neighbor.
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
field specifies the hop count to use when sending a
search request to this particular zone.
H.323 section:
Mode Determines whether H.323 calls are allowed to and
from the neighbor system.
Port The port on the neighbor system used for H.323
searches initiated from the local VCS.
SIP section:
Mode Determines whether SIP calls are allowed to and from
the neighbor system.
Port The port on the neighbor system used for outgoing
SIP messages initiated from the local VCS.
Transport Determines which transport type is used for SIP calls
to and from the neighbor system. The default is TLS.

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 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.
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).
