Grandstream Networks 200 Option 42 to, Override NTP, Distinctive, Ring Tone, Disable Call, Mode

Allow DHCP	DHCP Option 42 specifies a list of IP addresses for Network Time Protocol
Option 42 to	(NTP) servers available to the client. If you choose yes, BT200 will use the
override NTP	NTP servers resolved from DHCP, instead of the one you specified in the
server	"NTP Server" option above.
Distinctive	Customer Ring Tone 1 to 3 with associate Caller ID: when selected, if Caller
Ring Tone	ID is configured, then the device will ONLY sound this ring tone when the
	incoming call is from the Caller ID, device will use System Ring Tone for all
	other calls.
	When selected but no Caller ID is configured, the selected ring tone will be
	used for all incoming calls.
Disable Call	Default is No.
Waiting
Quick IP Call	This model has the ability to dial an IP address under the same LAN segment
Mode	by simply pressing the last octet in the IP address.
	In the Advanced Settings page there is an option "Use Quick IP-call mode",
	by default it is set to No. When this option is set to YES, and #XXX is
	dialed, where X is 0-9 and XXX <=255, phone will make direct IP call to
	aaa.bbb.ccc.XXX where aaa.bbb.ccc comes from the local IP address
	REGARDLESS of subnet mask.
	#XX or #X are also valid so leading 0 is not required (but OK).
	eg.
	192.168.0.2 calling 192.168.0.3 just dial #3 follow by SEND or #
	192.168.0.2 calling 192.168.0.23 just dial #23 follow by SEND or #
	192.168.0.2 calling 192.168.0.123 just dial #123 follow by SEND or #
	192.168.0.2 dial #3 and #03 and #003 has same effect --> call 192.168.0.3
	Note:- If you have a SIP Server configured, Direct IP-IP call will still work.
	However, if you are using STUN, Direct IP-IP call will also use STUN.
Lock keypad	If this parameter is set to “Yes”, the configuration updates via keypad for
update	Menu Item 7, 9, 12 are disabled.
