Configuring Traversal Server Zones - Cisco TelePresence Administrator's Manual

Zones and neighbors
Field Description
Accept proxied Controls whether proxied SIP registrations routed
registrations through this zone are accepted.
Media Controls the media encryption policy applied by the
encryption mode VCS for SIP calls (including interworked calls) to
and from this zone.
ICE support Controls whether ICE messages are supported by
the devices in this zone.
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:
Authentication Controls how the VCS authenticates incoming
policy 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.
Accept Controls whether this zone accepts delegated
delegated authentication requests.

Client settings section:
Retry interval The interval in seconds with which a failed attempt
to establish a connection to the traversal server
should be retried.
Location section:
Peer 1 to Peer 6 The IP address or FQDN of the traversal server.

If the traversal server is a VCS Expressway cluster,
this should include all of its peers.

Configuring traversal server zones

A VCS Expressway can act as a traversal server, providing firewall traversal on behalf of traversal clients (a
VCS Control).
To act as a traversal server, the VCS Expressway must have a special type of two-way relationship with
each traversal client. To create this connection, you create a traversal server zone on your local VCS
Expressway and configure it with the details of the corresponding zone on the traversal client. (The client
must also be configured with details of the VCS Expressway.)
After you have neighbored with the traversal client you can:

Usage tips
This setting only applies to registration
requests for a domain for which the
VCS is acting as a Registrar. For
requests for other domains the SIP
registration proxy mode setting
applies. See Proxying registration
requests for more information.
