Poison mode
Determines if SIP requests sent to systems located
via this zone are "poisoned" such that if they are
received by this VCS again they will be rejected.

Authentication section:

policy
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.

UDP / TCP probes section:
UDP retry
interval
interval
The frequency (in seconds) with which the client
sends a UDP probe to the VCS Expressway if a keep
alive confirmation has not been received.
sends a UDP probe to the VCS Expressway if a keep
alive confirmation has not been received.
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.

UDP retry count
The number of times the client attempts to send a
UDP probe to the VCS Expressway during call setup.

The interval (in seconds) with which the client sends
a UDP probe to the VCS Expressway after a call is
established, in order to keep the firewall’s NAT
bindings open.

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.
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:
■
apply transforms to alias search requests directed to that group of endpoints
■
control the bandwidth used for calls between your local VCS and each group of ENUM endpoints
section.
The configurable options for an ENUM zone are:
