Field Description
Username Traversal clients must always authenticate with
traversal servers by providing their authentication
credentials. The authentication username is the
name that the traversal client must provide to the
VCS Expressway.
If the traversal client is a VCS, this must be its
n
connection credentials Username as configured
in its traversal client zone.
If the traversal client is a TANDBERG Gatekeeper,
n
this is its System Name.
H.323 section:
Mode Determines whether H.323 calls are allowed to and
from the traversal client.
Protocol Determines the protocol (Assent or H.460.18) to use
to traverse the firewall/NAT.
Port The port on the local VCS Expressway to use for
H.323 calls to and from the traversal client.
H.460.19 Determines whether or not the same two ports are
demultiplexing used for media by two or more calls.
mode
On: all calls from the traversal client use the same
two ports for media.
Off: each call from the traversal client uses a
separate pair of ports for media.
SIP section:
Mode Determines whether SIP calls are allowed to and
from the traversal client.
Port The port on the local VCS Expressway to use for SIP
calls to and from the traversal client.
Transport Determines which transport type is used for SIP calls
to and from the traversal client. The default is TLS.
TLS verify Controls X.509 certificate checking and mutual
mode and authentication between this VCS and the traversal
subject name client.
If TLS verify mode is enabled, a TLS verify subject
name must be specified. This is the certificate
holder's name to look for in the traversal client's
X.509 certificate.

Zones and neighbors
Usage tips
There must also be an entry in the VCS
Expressway's local authentication
database for the client's authentication
username and password. To check the
list of entries and add it if necessary, go
to the Local authentication database
page. Either:
click on the Add/Edit local
n
authentication database
go to VCS configuration >
n
Authentication > Local database
See Firewall traversal protocols and
ports for more information.
This must be different from the listening
ports used for incoming TCP, TLS and
UDP SIP calls (typically 5060 and 5061).
See TLS certificate verification of
neighbor systems for more information.
