This seems to be a new problem for me, or at least something I wasn't aware of before. Sometimes when people try to call me, my phone won't even ring and the call will go directly to voicemail. I will be sitting at my desk working on a paper or something and my phone will be in my pocket doing nothing, but it don't indicate that anyone tried to call. This has happened three times that I know of, twice the call was from a landline and once the call was from a cell phone. It's kind of annoying to not be able to receive calls consistently. At first I thought it might have to do with my coverage, but it happens on both the Sprint network and when I roam on Verizon regardless of the number of bars I have on my phone. At my desk now, I have 3 bars on Sprint (or 6 on Verizon if I force roaming) and two of the three times I know I haven't received calls have been in this location. What's going on? Is this just something to accept because it seems to happen infrequently? Can Sprint even really do anything about this if I bring it to their attention?
