    56         * Calling this method triggers our internal timer so that

    57         * we get enough run time at the view's end to get our

    58         * method calls end properly. Otherwise we will fall into

    62         * This is a dirty hack I know. If you come up with a better

    63         * solution you are more than welcome to change this.

    64         * To test this works make a single call and send 'www456ppp'

    65         * DTMF string. If it doesn't crash in the target HW it works :)
