Controls how the VCS authenticates incoming
messages from this zone and whether they are
subsequently treated as authenticated,
unauthenticated, or are rejected. The behavior varies
for H.323 messages, SIP messages that originate
from a local domain and SIP messages that originate
from non-local domains.

The frequency (in seconds) with which the client

The default UDP and TCP probe retry
intervals are suitable for most situations.
However, if you experience problems
with NAT bindings timing out, they may
need to be changed.

Configuring ENUM zones
ENUM zones allow you to locate endpoints via an ENUM lookup. You can create one or more search rules
for ENUM zones based on the ENUM DNS suffix used and/or by pattern matching of the endpoints’ aliases.
for ENUM zones based on the ENUM DNS suffix used and/or by pattern matching of the endpoints’ aliases.
After you have configured one or more ENUM 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 ENUM endpoints
The configurable options for an ENUM zone are:
