Land Line Dialer Demo

This application allows you to dial on a landline a number you have in your Android device.

It works by beeps, each digit is assigned with a particular frequency sound, that's what you hear when you press the numbers on the land line keyboard. (DTMF)

The program generates the sequence of beeps corresponding to the entered phone number, the landline recognizes them and makes the call.

1. Enter the number you want to dial (or search for it in contacts)
2. Pick up the land line
3. Press DIAL central button
4. Put the device speaker close to landline's microphone

If it does not work (if there is no call):
* Make sure the sound direction is perpendicular to the micro
* Try turning up the volume
* Try changing the settings
* It may be a mobile speaker issue, try it again with an earphone or external speaker
* Check the land line configuration, the dialing method must be by tones, not by pulses
