Zones LocalZone SubZones SubZone [1..1000] Bandwidth Total Mode: <Limited/Unlimited/NoBandwidth>
Determines whether this subzone has a limit on the total bandwidth of calls being used by its endpoints at any
one time.
NoBandwidth: no bandwidth available. No calls can be made to, from, or within this subzone.
Default: Unlimited
Example: xConfiguration Zones LocalZone SubZones SubZone 1 Bandwidth Total Mode: Limited
Zones LocalZone SubZones SubZone [1..1000] Name: <S: 0, 50>
Assigns a name to this subzone.
Example: xConfiguration Zones LocalZone SubZones SubZone 1 Name: "BranchOffice"
Zones LocalZone SubZones SubZone [1..1000] Registrations: <Allow/Deny>
Controls whether registrations assigned to this subzone are accepted.
Default: Allow
Example: xConfiguration Zones LocalZone SubZones SubZone 1 Registrations: Allow
Zones LocalZone Traversal H323 Assent Mode: <On/Off>
Determines whether or not H.323 calls using Assent mode for firewall traversal will be allowed. Applies to
traversal-enabled endpoints registered directly with the VCS.
Default: On
Example: xConfiguration Zones LocalZone Traversal H323 Assent Mode: On
Zones LocalZone Traversal H323 H46018 Mode: <On/Off>
Determines whether or not H.323 calls using H460.18 mode for firewall traversal will be allowed. Applies to
traversal-enabled endpoints registered directly with the VCS.
Default: On
Example: xConfiguration Zones LocalZone Traversal H323 H46018 Mode: On
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
