Parameter	Description	Usage
OpFlags	Enables or disables various	Bit map, as follows:
	features on the phone.	• Bit 0 (mask 0x1)—If 1, ignore the
		DHCP-assigned TFTP file name and use the
		following file name when using TFTP for
		configuring: ffxxxxxxxxxxxx (Cisco IP Phone
		7902G) or ldxxxxxxxxxxxx (Cisco IP Phone
		models 7905G/7912G), where each xx is the
		two-digit lowercase hexadecimal representation
		of each integer in the phone’s MAC address.
		• Bit 1 (mask 0x2)—If the phone is configured to
		use static IP (that is, the router and gateway
		addresses are statically assigned), set to 1 to
		prevent probing at boot time. Otherwise, the
		phone probes the route/gateway address to
		determine if there is network connectivity.
		• Bit 2—Reserved for future use.
		• Bit 3 (mask 0x8)—If 1, do not request DHCP
		option 150 in the DHCP DISCOVERY message.
		• Bit 4 (mask 0x10)—If 1, assume operation
		under VLAN. (The VLAN ID is specified in the
		VLANSetting parameter.)
		• Bit 5 (mask 0x20)—If 1, turn off VLAN IP
		encapsulation.
		• Bit 6 (mask 0x40)—If 1, do not perform CDP1
		discovery.
		• Bit 7 (mask 0x80)—If 1, do not allow web
		configuration of the phone.
		• Bit 8 (mask 0x100)—Not used on the
		Cisco IP Phone 7905G. On the Cisco IP Phone
		7902G, if set to 1, the IP address cannot be
		refreshed through an HTTP request.
