Check this review for the Babyphone as a iPhone.

The main screen of Babyphone shows the current status, the microphone sensitivity and the threshold for triggering the alarm.

If the Microphone's display reaches or exceeds the set threshold, the previously defined phone number will be called. After completion of the call and the expiration of the delay Babyphone will reactivate itself again.

In the settings you can enter the number to call. In addition, there is a sleeping interval with an adjustable delay in minutes, after which Babyphone will reactivate itself again.
