How many different people do you call or get called by each day? Two? Ten? Tons? Either way, as long as you are among those who do not wonder why there is a phone in smartphone, you'll find the call log on Windows Phone a constant bother. This ironically owes to the log being just what the name suggests, a sequential list of entries. All telephone events are added to an ever growing queue of incoming calls, missed calls, and outgoing calls. There is no option to filter by one of the former categories, nor does Windows Phone allow you to narrow down call events to one contact.
So in case your best friend recently had a whinge about you not calling in weeks, good luck finding the call log entry proving that you indeed tried just a few days ago.
