Grandstream Networks HT502 Syslog Level, Download Device, Configuration, Profile Active

	Syslog Level	Select the HT502 to report the log level. Default is NONE. The level is one of DEBUG,
		INFO, WARNING or ERROR. Syslog messages are sent based on the following events:
		1.		product model/version on boot up (INFO level)
		2.		NAT related info (INFO level)
		3.		sent or received SIP message (DEBUG level)
		4.		SIP message summary (INFO level)
		5.		inbound and outbound calls (INFO level)
		6.		registration status change (INFO level)
		7.		negotiated codec (INFO level)
		8.		Ethernet link up (INFO level)
		9.		SLIC chip exception (WARNING and ERROR levels)
			10. memory exception (ERROR level)
		The Syslog uses USER facility. In addition to standard Syslog payload, it contains the
		following components:
		GS_LOG: [device MAC address][error code] error message
		Example: May 19 02:40:38 192.168.1.14 GS_LOG: [00:0b:82:00:a1:be][000] Ethernet link
		is up
	Download Device	Allows user to download and save a text file containing all the P values of each setting as
	Configuration	configured at that point on the unit.
TABLE 10: ACCOUNT SETTINGS
	Profile Active		When set to Yes the FXS port is activated.
	Primary SIP Server		SIP Server’s IP address or Domain name provided by VoIP service provider.
	Failover SIP Server		Failover SIP Server’s IP address or Domain name in case primary server does not
			respond.
	Prefer Primary SIP		Default is no. If set to yes it will register to Primary Server if registration with Failover
	Server		server expires
	Outbound Proxy		IP address or Domain name of Outbound Proxy, or Media Gateway, or Session Border
			Controller. Used by HT502 for firewall or NAT penetration in different network
			environments. If symmetric NAT is detected, STUN will not work and ONLY outbound
			proxy can correct the problem.
	SIP transport		User can select UDP or TCP or TLS.
	NAT Traversal (STUN)		This parameter defines whether or not the HT502 NAT traversal mechanism is
			activated. If activated (by choosing “Yes”) and a STUN server is also specified, then the
			HT502 performs according to the STUN client specification. Using this mode, the
			embedded STUN client will detect if and what type of firewall/NAT. If the detected NAT
			is a Full Cone, Restricted Cone, or a Port-Restricted Cone, the HT502 will use its
			mapped public IP address and port in all of its SIP and SDP messages.
			If the NAT Traversal field is set to “Yes” with no specified STUN server, the HT502 will
			periodically (every 20 seconds or so) send a blank UDP packet (with no payload data)
			to the SIP server to keep the “hole” on the NAT open.
	SIP User ID		User account information, provided by VoIP service provider (ITSP). Usually in the form
			of digit similar to phone number or actually a phone number.
	Authenticate ID		SIP service subscriber’s Authenticate ID used for authentication. Can be identical to or
			different from SIP User ID.
	Authenticate Password		SIP service subscriber’s account password.
	Name		SIP service subscriber’s name for Caller ID display.
