Calculator [Q] not receiving incoming google voice call notifications

I want to stop using a mobile carrier and instead use google voice since they give you your own number and its free to call and text message. my computer alerts me when someone calls my google number and texts, but on my android phone or my customized kindle fire hd i only receive a notification when someone texts me and not when someone calls. it just alerts me a minute later that i got a missed call, is their any way around this? I doubt it, but maybe some xda god knows how to tweak and fix the problem.
