All indicators supported by AT+CIND are accessible with this command, too. A detailed description of these indi- cators can be found there.

The following indicators are accessible via AT^SIND only:

	"audio"	Activity of the built-in audio unit.
		0	Audio unit not active.
		1	Value 1 means for example:
			Outgoing voice call: Indicator appears when dialing starts.
			Incoming voice call: Indicator appears prior to the RING result code.
	"vmwait1"	Voice Message Waiting Indication for line 1
		0	The value 0 notifies that no new voice message is available, and is pro-
			vided by the service center to clear the voice message indication after
			the subscriber has retrieved all voice messages.
		1	The value 1 notifies the subscriber that the mailbox contains one or
			several messages.
		"vmwait1" and "vmwait2" indicate the receipt of a special short message with
		a Voice Message Waiting Indicator. The service must be provisioned by the
		operator.
		The numbers 1 or 2 in "vmwait1" and "vmwait2" are related to the two lines of
		the Alternate Line Service (ALS), also defined in CPHS Phase 2 standard. For
		further details refer to the AT^SALS command.
		The presentation mode of the indicator varies with the operator: If more than
		one message are waiting, some operators only indicate the first one, others
		deliver the indicator each time a new voice message is put into the mailbox.
		After the subscriber has retrieved all voice messages the service center auto-
		matically sends another message indication which provides the value 0.
		Some operators may also send the number of waiting voice messages along
		with the indication. In this case, the number will be displayed by the MC55 as
		part of the URC. For example, "+CIEV: vmwait1,1,5" notifies that five new voice
		messages are waiting. However, it should be noted that neither the read com-
		mand AT^SIND? nor the write command AT^SIND=<mode>,2 display the
		number of waiting messages.
