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 VCS Border
Controller to be used for H.323 connections
from the client.
H.323 protocol
Determines which of the two firewall traversal
protocols will be used for calls through the
firewall, to and from the client. The same
protocol must be used by the client.
SIP mode
Determines whether SIP calls will be allowed
to and from the traversal client.
SIP port
Specifies the port on the VCS Border
Controller to be used for SIP calls from this
traversal client.
SIP transport
Determines which transport type will be used
for SIP calls to and from the traversal client.
Authentication username
If the traversal client is a VCS, this must be
the VCS’s Authentication Username. If the
traversal client is a gatekeeper, this must be
the gatekeeper’s System Name.
H.460.19 demux mode
Determines whether or not the same two ports
can be used for media by two or more calls
from the traversal client.
On: allows use of the same two ports for
media for all calls.
Off: each call will use a separate pair of ports
for media.
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
keep the firewall’s NAT bindings open.
TCP retry count
Sets the number of times the traversal client
will attempt to send a TCP probe to the VCS.
TCP retry interval
Sets the frequency (in seconds ) with which
the traversal client will send a TCP probe to
the VCS.
UDP keep alive interval
Sets the interval (in seconds) with which the
traversal client will send a UDP probe to the
VCS once a call is established, in order to
keep the firewall’s NAT bindings open.
UDP retry count
Sets the number of times the traversal client
will attempt to send a UDP probe to the VCS
Border Controller.
UDP retry interval
Sets the frequency (in seconds) with which
the traversal client will send a UDP probe to
the VCS Border Controller.
