Configuring the VCS as a Traversal Server
TANDBERG VIDEO COMMUNICATIONS SERVER ADMINISTRATOR GUIDE
Configuring Traversal for Endpoints
Overview
To configure the options for these endpoints:
•VCS Configuration > Expressway> Locally
Registered Endpoints
You will be taken to the Locally Registered Endpoints page.
•xConfiguration Zones LocalZone Traversal H323
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 Expressway 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 Expressway uses.

Firewall
Traversal
UDP probe retry interval
Sets the frequency (in seconds) with which locally registered endpoints will send a UDP probe to the VCS Expressway.
UDP probe retry count
Sets the number of times locally registered endpoints will attempt to send a UDP probe to the VCS Expressway.
UDP probe keep alive interval
Sets the interval (in seconds) with which locally registered endpoints will send a UDP probe to the VCS Expressway once a call is established, in order to keep the firewall’s NAT bindings open.
TCP probe retry interval
Sets the frequency (in seconds) with which locally registered endpoints will send a TCP probe to the VCS Expressway.
TCP probe retry count
Sets the number of times locally registered endpoints will attempt to send a TCP probe to the VCS Expressway.
TCP probe keep alive interval
Sets the interval (in seconds) with which locally registered endpoints will send a TCP probe to the VCS Expressway once a call is established, in order to keep the firewall’s NAT bindings open.
