Is the incoming call displayed on the phone though? Are you saying there is just no audible alert? And if so, do you hear anything through the headset?

Check Start | Settings | Voice Command. Try unchecking the Phone setting temporarily and see if that resolves the issue. If it does adjust the options for the VC Phone Notifications. To be honest I just don't recall whether my phone rings or not when my BT headset is open...and I don't have it handy to try it out.
