Mike, you've helped me in the past, perhaps you could do so once more with Tasker.
I have the Priority Caller profile set up, but I'd like to be able to have the volume go up in steps, as in my work environment, having the phone blare out at max volume isn't such a great thing.
Currently the steps I use are:
Profile: Priority Caller
Context: Incoming Call
1. Enter Task Action: Silent Mode
2. Enter Task Action: Vibrate on Ringer
3. Enter Task Action: Ringer Volume
4. Enter Task Action: Say
Thanks.
