stop phonecall before voicemail
<p>Is it possible in Android to make a service that stops the phone-call when the voice-mail is almost reached so that the user is not billed for the connection cost on the mobile network? </p>

<p>I was looking to let the service recognize the voice-mail but how can i let the app know the difference between a normal call and a voice-mail call? </p>

<p>Thanks for your answer(s)</p>
