				Chapter 5 Linksys IP Phone Field Reference
	932 Tab (SPA962 only)
Unit 1
Field		Description
Unit 1 Key 1-32		This field lets you enter a string that defines the extension and other parameters associated
		with each lighted button on the first SPA932 unit. Keywords and values are case-sensitive.
		The configuration script is composed of the following keywords, followed by an equal
		sign (=) and separated by semicolons (;):
		• fnc—defines which of the following functions are enabled for the specified key
			(separate more than one function with a plus sign (+):
			– blf—busy lamp field function used for monitoring line activity
			– sd—speed dial function
			– cp—call pickup (if supported by the SIP proxy server)
		• sub—Use this keyword to identify the phones to be monitored.
		• usr —Use this keyword to identify the specific users or extensions to be monitored.
		• nme—(optional) Use this field with the SPA9000 to identify any alias that has been
			assigned to the extension in the Linksys IP phone configuration.
		• vid—(optional) Use this field to identify the SPA962 extension to use with the
			monitored list specified by the sub= keyword, when more than one BLF monitored
			list is configured on the SIP proxy server. The possible values are 1 to 6,
			corresponding to each of the six extensions available on the SPA962.
			Note You only need to use the vid= keyword in the first entry assigned to each
				SPA962 extension. Subsequent keys will use the same extension.
		The following is the syntax for a Broadsoft server:
		fnc=enabled_functions;sub=blf_list_uri@broadsoft;usr=dn@broadsoft
		Replace the variables (in italics), as follows:
		• enabled_functions with cp for call pickup, sd for speed dial, and blf for busy lamp
			field; separate multiple functions in any order with a plus sign (+)
		• blf_list_uri with the URI assigned to the BLF monitoring list on the Broadsoft
			server.
		• broadsoft with the IP address or hostname of the Broadsoft server.
		• dn with the number associated with the user account on the Monitored Users list.
		For example:
		fnc=sd+blf;sub=marketing@192.168.100.1;usr=reception@192.168.100.1
		Note The nme keyword is not used because the Broadsoft server automatically uses the
			assigned user account name.
