Field Description
Port The port on the traversal server to use for H.323 calls
to and from the local VCS.
SIP section:
Mode Determines whether SIP calls are allowed to and from
the traversal server.
Port The port on the traversal server to use for SIP calls to
and from the VCS.
This must be different from the listening ports used
for incoming TCP, TLS and UDP SIP calls (typically
5060 and 5061).
Transport Determines which transport type is used for SIP calls
to and from the traversal server. The default is TLS.
TLS verify Controls X.509 certificate checking and mutual
mode authentication between this VCS and the traversal
server when communicating over TLS.
Accept Controls whether proxied SIP registrations routed
proxied through this zone are accepted.
registrations
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.
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.

Usage tips
For firewall traversal to work via H.323,
the traversal server must have a
traversal server zone configured on it to
represent this VCS, using this same port
number.
For firewall traversal to work via SIP, the
traversal server must have a traversal
server zone configured on it to represent
this VCS, using this same transport type
and port number.
See TLS certificate verification of
neighbor systems for more information.
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
information.
See Authentication Policy configuration
options for more information.
