•xConfiguration Zones Zone

Authentication username

If the traversal client is a VCS, this must be the VCS’s Authentication Username. If the traversal client is a gatekeeper, this must be the gatekeeper’s System Name.

H.323 mode

Determines whether H.323 calls will be allowed to and from the traversal client.

H.323 protocol

Determines which of the two firewall traversal protocols will be used for calls through the firewall, to and from the client. The same protocol must be used by the client.

H.323 port

Specifies the port on the VCS Border Controller to be used for H.323 connections from the client.

H.460.19 demux mode

Determines whether or not the same two ports can be used for media by two or more calls from the traversal client.

On: allows use of the same two ports for media for all calls.

Off: each call will use a separate pair of ports for media.

SIP mode

Determines whether SIP calls will be allowed to and from the traversal client.

SIP port

Specifies the port on the VCS Border Controller to be used for SIP calls from this traversal client.

SIP transport

Determines which transport type will be used for SIP calls to and from the traversal client.

UDP retry interval

Sets the frequency (in seconds) with which the traversal client will send a UDP probe to the VCS Border Controller.

UDP retry count

Sets the number of times the traversal client will attempt to send a UDP probe to the VCS Border Controller.

UDP keep alive interval

Sets the interval (in seconds) with which the traversal client will send a UDP probe to the VCS once a call is established, in order to keep the firewall’s NAT bindings open.

TCP retry interval

Sets the frequency (in seconds ) with which the traversal client will send a TCP probe to the VCS.
