Determines whether the Expressway's B2BUA

Authentication section:
Authentication
policy
policy
Controls how the Expressway 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.

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.

6 address
The IP address or FQDN of the traversal server.
If the traversal server is an Expressway-E
cluster, this should include all of its peers.

Configuring Traversal Server Zones
An Expressway-E can act as a traversal server, providing firewall traversal on behalf of traversal clients (an
Expressway-C).
Expressway-C).
For firewall traversal to work, the traversal server (Expressway-E) must have a special type of two-way relationship
with each traversal client. To create this connection between a Expressway-E and a Expressway-C, see
with each traversal client. To create this connection between a Expressway-E and a Expressway-C, see
. For full details on how traversal client zones and traversal server zones work
Note:
After you have neighbored with the traversal client you can:
■
provide firewall traversal services to the traversal client
■
query the traversal client about its endpoints
