Here's what I'm using for priority callers:
EscAlert (374)
A1: Vibrate On Ringer
A2: Silent Mode
A3: Ringer Volume If
A4: Wait
A5: Ringer Volume If
A6: Wait
A7: Ringer Volume If
A8: Wait
A9: Ringer Volume
I use this with an incoming call context, so that when the call is complete, the volumes go back to normal.
