Usage tips
Accept proxied
registrations
Controls whether proxied SIP registrations routed
through this zone are accepted.
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.
Media
encryption mode
Controls the media encryption policy applied by the
VCS for SIP calls (including interworked calls) to
and from this zone.
See
Configuring media encryption
policy [p.135]
for more information.
ICE support
Controls whether ICE messages are supported by
the devices in this zone.
See
Configuring ICE messaging
support [p.137]
for more information.
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
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.
See
Authentication policy configuration
options [p.105]
for more information.
Accept
delegated
credential
checks
Controls whether this zone accepts delegated
authentication requests.
See
Configuring delegated credential
checking (SIP only) [p.109]
for more
information.
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
address
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.
See
Neighboring the local VCS to
another VCS cluster [p.169]
for more
information.
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:
