Configuring the VCS as a Traversal Client

Retry interval

Specifies the interval in seconds with which a failed attempt to establish a connection to the traversal server should be retried.

H.323 mode

Determines whether H.323 calls will be allowed to and from this zone.

H.323 protocol

Determines which of the two firewall traversal protocols to use for calls to the traversal server.

H.323 port

Specifies the port on the traversal server to be used for H.323 firewall traversal calls.

SIP mode

Determines whether SIP calls will be allowed to and from this zone.

SIP port

Specifies the port on the traversal server to be used for SIP calls from this VCS

SIP transport

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

Remember to Save your changes.			Primary address
			Specifies the IP address or FQDN of the
			traversal server.
