IS-101 Voice Mode AT Commands

Table 25. Voice Mode Command Descriptions (Continued)

Command	Default		Description

		Volume Selection: This command sets the volume level for the modem’s playback voice mode. A
		different playback level may be needed for each type of playback device (telephone line, local handset,
+VGT=m	128	local telephone, or speaker).

		Range: 121–131
		128*	Nominal transmit level

+VIP	none	Initialize Parameter: This command causes the modem to initialize all voice parameters to the factory
		default values. This command does not change relay or speaker setup (that is, if the modem is off-
		hook, then the modem remains off hook after processing this command).

		DTE/DCE Inactivity Timer: This command sets the length of time the modem can be inactive in voice
		mode before the modem resets its relays +VLS=0 and changes to data mode (FCLASS=0) with
		autobauding. The purpose of this timer is to ensure that the DTE does not leave the DCE in a mode
		that cannot be accessed by voice-unaware software. This timer is supported in playback, record and
+VIT=m	0	voice command mode. Sending any data (such as a <DLE><NUL> string) to the modem re-initializes
		this timer.

		Range: 0–255 (units of 1.0 second)
		m = 0*	Disables inactivity timer
		m ≠ 0	Inactivity timer active

NOTE: An asterisk (*) denotes the factory-default setting.
