Missed calls notification

Hi guys,

I only got 1+2 just a day back and am still trying to set it up.. So please bear with me..

If my phone is locked and i get some voice call which i didn't answer, then it is treating it as missed call.

But when my phone is unlocked and get voice call which i didn't answer, 1+2 is not treating as a missed call. It is treating it as received call. Is it just me ? Is there any app to treat it as missed call.

Thanks !!!
