Field Description Usage tips
Type The nature of the specified zone, in relation to the local VCS. Select
ENUM.
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 Hop counts 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.
DNS
suffix
The domain to be appended to the transformed E.164 number to
create an ENUM domain for which this zone is queried.
H.323
mode
Determines whether H.323 records are looked up for this zone.
SIP
mode
Determines whether SIP records are looked up for this zone.
Configuring DNS zones
DNS zones allow you to locate endpoints via a DNS lookup. You can create one or more search rules for
DNS zones based on pattern matching of the endpoints’ aliases.
After you have configured one or more DNS zones, you can:
n apply transforms to alias search requests directed to that group of endpoints
n control the bandwidth used for calls between your local VCS and each group of DNS endpoints
See About URI dialing [p.203] for more information on configuring and using DNS zones.
The configurable options for a DNS zone are:
