Tasker - Vibrate then ring profile

Dear All,
I purchased Tasker a month ago and have been struggling since then to create a profile that will enable "vibrate and then ring" for incoming calls. I have spent hours and hours on google trying to find a "recipe" and have not been able to find. I have also looked into the tutorials. To cut it short, I have done my homework, however am unable to succeed. Hope one of Gurus can help me out.

I have created a state, phone, incoming call, then chose task with the following:
1. silence ringer
2. vibrate for 200 ms
3. wait 3 seconds
4. ringer volume 7

The idea is to vibrate for about 2 or 3 seconds and then ring loud. I understand that step 2 and 3 might add up to 5 seconds. The scenario does not change even if the step 2 or 3 is alone removed

WHen call comes, the default android ringer comes alive and so it does not silence the ringer or vibrate. If I silence the ringer using the android default sound settings then no sound comes. In other words, the default sound settings from Android seems to supersede the settings of Tasker. I am able to see a screen (when call arrives) where I am able to see points 1 to 4 (seen above) as profile.

Can you please help me to achieve vibrate and ring please...

with regards,
Elango
