I had the same issue on my RAZR MAXX when I was having network dropping issues (*prior to the JB update). Would have voicemail, but no record of call. Didn't happen all of the time, but narrowed it down to my phone dropping the network connection. Live in a fringe area and hand off from 4G to 3G frequently occurred in certain areas of my house. The problem was that the handoff resulted in multiple drops of the network connection, some lasting for as long as 2-3 minutes. Even on Wifi, had same issue and I believe that is because calls come across the 3G connection. I could be wrong about that, but think that because if 3G only, cannot surf net and talk at same time. But if on 4G or Wifi, can do both.
Also - does this happen in multiple locations or just in a specific place (Home, certain parts of home, work, etc...). Would monitor your signal. If the phone has an alert you can set when you lose the network, it may help you identify if that is the issue.
As @eaccents indicated, a new SIM may be a good starting point. This did help mine some, but not completely.
*Only the update to JB completely resolved the issue.
