Zones Zone [1..1000] TraversalClient H323 Port: <1024..65534>
Specifies the port on the traversal server to be used for H.323 firewall traversal calls from this VCS. If the
traversal server is a VCS Expressway, this must be the port number that has been configured on the VCS
Expressway's traversal server zone associated with this VCS.
Example: xConfiguration Zones Zone 4 TraversalClient H323 Port: 2777
Zones Zone [1..1000] TraversalClient H323 Protocol: <Assent/H46018>
Determines which of the two firewall traversal protocols will be used for calls to and from the traversal server.
Note: the same protocol must be set on the server for calls to and from this traversal client.
Default: Assent
Example: xConfiguration Zones Zone 4 TraversalClient H323 Protocol: Assent
Zones Zone [1..1000] TraversalClient Peer [1..6] Address: <S:0,128>
Specifies the IP address or Fully Qualified Domain Name (FQDN) of the traversal server. If the traversal server
is a VCS Expressway cluster, this will be one of the peers in that cluster.
Example: xConfiguration Zones Zone 4 TraversalClient Peer 1 Address:
"10.192.168.1"
Zones Zone [1..1000] TraversalClient Registrations: <Allow/Deny>
Controls whether proxied SIP registrations routed through this zone are accepted.
Default: Allow
Example: xConfiguration Zones Zone 4 TraversalClient Registrations: Allow
Zones Zone [1..1000] TraversalClient RetryInterval: <1..65534>
Specifies the interval (in seconds) with which a failed attempt to establish a connection to the traversal server
should be retried.
Default: 120
Example: xConfiguration Zones Zone 4 TraversalClient RetryInterval: 120
Zones Zone [1..1000] TraversalClient SIP Poison Mode: <On/Off>
Determines whether SIP requests sent out to this zone will be "poisoned" such that if they are received by the
local VCS again they will be rejected.
On: SIP requests sent out via this zone that are received again by this VCS will be rejected.
Off: SIP requests sent out via this zone that are received by this VCS again will be processed as normal.
Default: Off
Example: xConfiguration Zones Zone 4 TraversalClient SIP Poison Mode: Off
Zones Zone [1..1000] TraversalClient SIP Port: <1024..65534>
Specifies the port on the traversal server to be used for SIP calls from this VCS. If your traversal server is a
VCS Expressway, this must be the port number that has been configured in the traversal server zone for this
VCS.
Example: xConfiguration Zones Zone 4 TraversalClient SIP Port: 5061
