Zones LocalZone Traversal H323 H46019 Demultiplexing Mode: <On/Off>
Determines whether the VCS will operate in Demultiplexing mode for calls from traversal-enabled endpoints
registered directly with it.
On: allows use of the same two ports for all calls.
Off: each call will use a separate pair of ports for media.
Default: Off
Example: xConfiguration Zones LocalZone Traversal H323 H46019 Demultiplexing Mode:
Off
Zones LocalZone Traversal H323 Preference: <Assent/H46018>
If an endpoint that is registered directly with the VCS supports both Assent and H460.18 protocols, this
setting determines which the VCS uses.
Default: Assent
Example: xConfiguration Zones LocalZone Traversal H323 Preference: Assent
Zones LocalZone Traversal H323 TCPProbe KeepAliveInterval: <1..65534>
Sets the interval (in seconds) with which a traversal-enabled endpoint registered directly with the VCS will
send a TCP probe to the VCS once a call is established, in order to keep the firewall's NAT bindings open.
Default: 20
Example: xConfiguration Zones LocalZone Traversal H323 TCPProbe KeepAliveInterval: 20
Zones LocalZone Traversal H323 TCPProbe RetryCount: <1..65534>
Sets the number of times traversal-enabled endpoints registered directly with the VCS will attempt to send a
TCP probe to the VCS.
Default: 5
Example: xConfiguration Zones LocalZone Traversal H323 TCPProbe RetryCount: 5
Zones LocalZone Traversal H323 TCPProbe RetryInterval: <1..65534>
Sets the frequency (in seconds) with which traversal-enabled endpoints registered directly with the VCS will
send a TCP probe to the VCS.
Default: 2
Example: xConfiguration Zones LocalZone Traversal H323 TCPProbe RetryInterval: 2
Zones LocalZone Traversal H323 UDPProbe KeepAliveInterval: <1..65534>
Sets the interval (in seconds) with which a traversal-enabled endpoint registered directly with the VCS will
send a UDP probe to the VCS once a call is established, in order to keep the firewall's NAT bindings open.
Default: 20
Example: xConfiguration Zones LocalZone Traversal H323 UDPProbe KeepAliveInterval: 20
Zones LocalZone Traversal H323 UDPProbe RetryCount: <1..65534>
Sets the number of times traversal-enabled endpoints registered directly with the VCS will attempt to send a
UDP probe to the VCS.
Default: 5
Example: xConfiguration Zones LocalZone Traversal H323 UDPProbe RetryCount: 5
