Configuring Traversal Client Zones - Cisco TelePresence Administrator's Manual

Zones and neighbors
Field Description
Zone profile Determines how the zone's advanced settings
are configured.
Default: uses the factory default profile.
Custom: allows you to configure each setting
individually.
Alternatively. choose one of the preconfigured
profiles to automatically use the appropriate
settings required for connections to that type of
system. The options include:
Cisco Unified Communications Manager
n
Cisco Unified Communications Manager
n
(8.6.1 or later)
Nortel Communication Server 1000
n
Infrastructure device (typically used for non-
n
gatekeeper devices such as an MCU)

Configuring traversal client zones

To traverse a firewall, the VCS must be connected with a traversal server (typically, a VCS Expressway).
In this situation your local VCS is a traversal client, so you create a connection with the traversal server by
creating a traversal client zone on your local VCS. You then configure the client zone with details of the
corresponding zone on the traversal server. (The traversal server must also be configured with details of the
VCS client zone.)
After you have neighbored with the traversal server you can:
use the neighbor as a traversal server
n
query the traversal server about its endpoints
n
apply transforms to any queries before they are sent to the traversal server
n
control the bandwidth used for calls between your local VCS and the traversal server
n
For full details on how traversal client zones and traversal server zones work together to achieve firewall
traversal, see About firewall traversal
An NTP server must be configured for traversal zones to work.
The configurable options for a traversal client zone are:
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 Traversal client.

Usage tips
See Zone configuration: advanced settings
[p.151] for details on the advanced settings.
Only use the Custom profile to configure the
individual advanced settings on the advice of
Cisco customer support.

Communications Manager profiles.
Usage tips
After a zone has been created, the
Type cannot be changed.
