Field	Description
Type	The type defines the format in which the card alias is
	sent to the gatekeeper. Each alias can be of a
	different type:
	• H.323 ID (alphanumeric ID)
	• E.164 (digits 0-9, * #)
	• URL ID (URL style address)
	• Transport ID (IP address: port number)
	• Email ID (email address format)
	• Party Number (identical to the E.164 format)
	Note: Although all types are supported, the type of
	alias to be used depends on your gatekeeper’s
	capabilities.

c.Click the Fixed Ports & NAT button to configure the NAT for each span—as each mapped IP should be known to the firewall—and the fixed signaling and media ports. Selecting Fixed Ports allows you to define the ports that are allocated in the firewall to multimedia (audio, video and data) conference calls.
