Configuring Enum Zones - Cisco TelePresence Video Communication Server Administrator's Manual

Field Description
Authentication Controls how the VCS authenticates
policy 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 The frequency (in seconds) with which the
interval client sends a UDP probe to the VCS
Expressway if a keep alive confirmation has
not been received.
UDP retry The number of times the client attempts to
count send a UDP probe to the VCS Expressway
during call setup.
UDP keep The interval (in seconds) with which the
alive interval client sends a UDP probe to the VCS
Expressway after a call is established, in
order to keep the firewall's NAT bindings
open.
TCP retry The interval (in seconds) with which the
interval traversal client sends a TCP probe to the
VCS Expressway if a keep alive confirmation
has not been received.
TCP retry The number of times the client attempts to
count send a TCP probe to the VCS Expressway
during call setup.
TCP keep alive The interval (in seconds) with which the
interval traversal client sends a TCP probe to the
VCS Expressway when a call is in place, in
order to maintain the firewall's NAT bindings.

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.
After you have configured one or more ENUM zones, you can:
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
n
Full details of how to use and configure ENUM zones are given in the
The configurable options for an ENUM zone are:

configuration options for more
information.
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.
