BlackBerry Curve 8300

If I go to Profiles>Advanced>Normal>scroll down to 'Phone'> there is not an option for number of 'beeps' as there is in other options such as Messenger - Alert or MMS because the assumption is that the phone will continue to ring until it is answered or goes to VM. So if I have it set to Vibrate+Tone it should vibrate 3 times (or however many I have it set to) then have an audible ring until I pickup or it goes to VM just as on the Pearl where I set it to Vibrate twice then my regular ringtone would sound until I picked-up.
