Traversal
Configuring the VCS as a Traversal Server
Configuring Traversal for Endpoints
Traversal-enabled H.323 endpoints can
register directly with the VCS Border Controller
and use it for firewall traversal.
To configure the options for these endpoints:
VCS Configuration > Border Controller >
Locally Registered Endpoints
You will be taken to the Locally Registered
Endpoints page.

•
H.323 Assent mode
Determines whether or not H.323 calls using
Assent mode for firewall traversal will be
allowed.
H.460.18 mode
Determines whether or not H.323 calls using
H.460.18/19 mode for firewall traversal will
be allowed.
H.460.19 demux mode
Determines whether the VCS will operate in
Demultiplexing mode for calls from locally
registered endpoints.
On: allows use of the same two ports for all
calls.
Off: Each call will use a separate pair of ports
for media.
H.323 preference
If an endpoint supports both Assent and
H.460.18 protocols, this setting determines
which the VCS uses.
UDP probe retry interval
Sets the frequency (in seconds) with which
locally registered endpoints will send a UDP
probe to the VCS Border Controller.
UDP probe keep alive interval
Sets the interval (in seconds) with which
locally registered endpoints will send a UDP
probe to the VCS once a call is established, in
order to keep the firewall’s NAT bindings open.
UDP probe retry count
Sets the number of times locally registered
endpoints will attempt to send a UDP probe.
TCP probe retry interval
Sets the frequency (in seconds) with which
locally registered endpoints will send a TCP
probe to the VCS.
TCP probe keep alive interval
Sets the interval (in seconds) with which
locally registered endpoints will send a TCP
probe to the VCS once a call is established, in
order to keep the firewall’s NAT bindings open.
TCP probe retry count
Sets the number of times locally registered
endpoints will attempt to send a TCP probe to
the VCS.
