Also, make sure you have the latest prl by clicking on the update prl icon on the settings/system menu.
The sound or vibration you feel/hear when making a call is a notification that the call is connected. You can turn this off if you want in phone options. Also, when you make/receive a call the icon will always change to 1x on the taskbar. The Ev only comes into play for data.
I concur with hypnotic that you should probably flash the stock rom and then flash back to a custom rom if you want. Good Luck!
