2.4. Marco Conceptual
SIP mode
Determines whether SIP calls will be allowed to and from the neighbor zone.
H.323 mode
Determines whether H.323 calls will be allowed to and from the neighbor zone.
This must be the same port number as that configured on the neighbor system as its SIP TCP or SIP TLS port
(depending on which SIP transport mode is in use).
This must be the same port number as that configured on the neighbor system as its H.323 UDP port.

H.323 protocol
Determines which of the two firewall traversal protocols (Assent or H.460.18) to use for calls to the traversal server. (See Firewall Traversal Protocols for more information.)
H.323 port
Specifies the port on the traversal server to be used for H.323 calls to and from the local VCS.
SIP transport
Determines which transport type will be used for SIP calls to and from the traversal server. SIP port
Specifies the port on the traversal server to be used for SIP calls to and from the VCS. Retry interval
Specifies the interval in seconds with which a failed attempt to establish a connection to the traversal server should be retried.
Primary address
Specifies the IP address or FQDN of the traversal server.
Alternate 1 to Alternate 5 address Specifies the IP addresses or FQDNs of any alternates configured on the traversal server. H.323 mode
Determines whether H.323 calls will be allowed to and from the traversal server.
SIP mode
Determines whether SIP calls will be allowed to and from this zone.
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.
For full details on how traversal client zones and traversal server zones work together to achieve firewall traversal, see Firewall Traversal.

Sets the frequency (in seconds) with which the client will send a UDP probe to the traversal server if a keep alive confirmation has not been received.
UDP retry count
Sets the number of times the client will attempt to send a UDP probe to the VCS Border Controller during call setup. UDP keep alive interval
Sets the interval (in seconds) with which the client will send a UDP probe to the VCS Border Controller once a call is established, in order to keep the firewall’s NAT bindings open. TCP retry interval
Sets the frequency (in seconds ) with which the traversal client will send a TCP probe to the VCS during call setup.
TCP retry count
Sets the number of times the client will attempt to send a TCP probe to the VCS Border Controller during call setup.
TCP keep alive interval Sets the interval (in seconds) with which the traversal client will send a TCP probe to the VCS once a call is established, in order to maintain the firewall’s NAT bindings.
H.323 protocol
Determines the protocol (Assent or H.460.18) to be used to traverse the firewall/NAT. (See Firewall Traversal Protocols for more information.)
H.460.19 demultiplexing Mode Determines whether or not the same two ports can be used for media by two or more calls.
On: all calls will use the same two ports. Off: each call will use a separate pair of ports.
SIP port
Specifies the port on the local VCS Border Controller to be used for SIP calls to and from the traversal client.
SIP transport
Determines which transport type will be used for SIP calls to and from the traversal client.
Configuring Traversal Server Zones
SIP mode
Determines whether SIP calls will be allowed to and from this zone.
H.323 mode
Determines whether H.323 calls will be allowed to and from the traversal client.
H.323 port
Specifies the port on the local VCS to be used for H.323 calls to and from the traversal client.
Authentication username
If the traversal client is a VCS, this is its Authentication Username. If the traversal client is a gatekeeper, this is its System Name. There must
be an entry in the local VCS’s
Authentication database for this username. See Authentication for more information.
The default UDP and TCP probe retry intervals are suitable for most situations. However, if you experience problems with NAT bindings timing out, they may need to be changed.
