	Status	Whether the SIP ALG is “enabled” or “disabled” on the router
		or switch.
	CALL-ID translation	Whether Call-ID translation is “enabled” or “disabled” on
		router or switch. When enabled, the IP address portion of the
		Call-ID field is translated from a private IP address to the global,
		routable IP address of router or switch. The router or switch
		only translates this when the session is initiated by a device
		within the private network protected by the firewall.

		information about the current audio sessions for each SIP
		session.

		address of the device that initiated the SIP session.
	TO	The SIP URI address of the device that received the SIP session
		request.
	TO tag	The tag number assigned to the SIP session by the device that
		received the SIP session request. The router or switch uses this,

		SIP session.
	FROM	The SIP URI address of the device that initiated the SIP session
		request.
	FROM tag	The tag number assigned to the SIP session by the device that
		initiated the SIP session request. The router or switch uses this,

		initiated the call. "Private" indicates a device located within the

		the firewall initiated a SIP session to a device on the public side
		of the firewall.
