Zones LocalZone Traversal H323 H46019 Demultiplexing Mode: <On/Off>
Controls whether the VCS operates in Demultiplexing mode for calls from traversal-enabled endpoints registered directly with it.
Default: Off .
On: allows use of the same two ports for all calls.
Off: each call will use a separate pair of ports for media.
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. 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.
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. Default: 5 .
Example: xConfiguration Zones LocalZone Traversal H323 UDPProbe RetryCount: 5
Zones LocalZone Traversal H323 UDPProbe RetryInterval: <1..65534>
Sets the frequency (in seconds) with which traversal-enabled endpoints registered directly with the VCS will send a UDP probe.
Default: 2 .
Example: xConfiguration Zones LocalZone Traversal H323 UDPProbe RetryInterval: 2
Zones LocalZone TraversalSubZone Bandwidth PerCall Limit: <1..100000000>
The bandwidth limit (in kbps) applied to any one traversal call being handled by the VCS (applies only if the mode is set to Limited).
Default: 1920 .
Example: xConfiguration Zones LocalZone TraversalSubZone Bandwidth PerCall Limit: 1920
Zones LocalZone TraversalSubZone Bandwidth PerCall Mode: <Limited/Unlimited/NoBandwidth>
Determines whether there is a limit on the bandwidth of any one traversal call being handled by the VCS. Default: Unlimited.
NoBandwidth: no bandwidth available. No traversal calls can be made.
Example: xConfiguration Zones LocalZone TraversalSubZone Bandwidth PerCall Mode: Limited
