Ring type <rt/>

Ring type is used to define a simple class of ring to be applied based on some credentials that are usually carried within the network protocol. The ring class includes attributes such as call-waiting and ringer index, if appropriate. The ring class can use one of four types of ring that are defined as follows:

	ring			Play a specified ring pattern or call waiting indication.
	visual			Provide only a visual indication (no audio indication) of incoming call (no
				ringer needs to be specified).
	answer			Provide auto-answer on incoming call.
	ring-answer			Provide auto answer on incoming call after a ring period.
Note
			The auto-answer on incoming call is currently only applied if there is no other call in
			progress on the phone at the time.
		In the following table, x is the ring class number. The x index needs to be
		sequential.
Attribute			Permitted Values		Interpretation
se.rt.enabled			0,1		Set to 1 to enable the ring type feature within the
					phone, 0 otherwise.
se.rt.modification.enabled			0,1		Set to 1 to allow user modification through local
					user interface of the pre-defined ring type enabled
					for modification.
se.rt.x.name			UTF-8 encoded string		Used for identification purposes in the user
					interface.
se.rt.x.type			ring OR visual OR answer		As defined in table above.
			OR ring-answer
se.rt.x.ringer			integer - only relevant if the		The ringer index to be used for this class of ring.
			type is set to ‘ring’ or		The ringer index should match one of Ringer
			‘ring-answer’		Patterns on page A-31.
se.rt.x.callWait			integer - only relevant if the		The call waiting index to be used for this class of
			type is set to ‘ring’ or		ring. The call waiting index should match one
			‘ring-answer’		defined in Call Progress Patterns on page A-30.
se.rt.x.timeout			positive integer - only		The duration of the ring in milliseconds before the

			value is 2000.
se.rt.x.mod			0,1		Set to 1 if the user interface should allow for
					modification by the user of the ringer index used for
					this ring class.
