Motorola RAZR2 V9m

Is anyone else experiencing a lot of dropped calls with the Razr2? I have made several calls to someone on a landline while sitting in my office, with full signal, and for no apparent, the call went silent on both ends. It would work fine for a few minutes, then the calls would get dropped. Is this just a bad phone I got, or are others having this problem.
I called Verizon, and they suggested making sure I don't cover the antenna area with my fingers, near the hinges.
