Description

Local phone Telco line Internal microphone External microphone

Internal speaker (requires squelch on any microphone activ- ity)

External speaker (requires squelch on any microphone activ- ity)

External microphone and speaker combination (handset or headset)

Note: For speakerphone applications, see ATI10, +VSP, and “Speakerphone

			AT Command Requirements” in the Voice Application Note for more
			details.

		Automatic Hang-Up Control: This command changes the way the modem re-
		sponds to hang-up commands after it switches from voice mode to fax or data
		modes.
		n = 0–2
+VNH=n	0	n = 0*	The modem retains automatic hang-ups as normal in data and
			fax modes
		n = 1	The modem disables automatic hang-ups usually found in non-
			voice modes
		n = 2	The modem disables all automatic hang-ups usually found in
			non-voice modes except a ‘logical’ hang-up
