Verizon, iPhone 5 and Dead Calls

I switched to Verizon on an iPhone 5 from an AT&T iPhone 4S. I never had issues with dropped calls around the Boston and Nashua areas. I had weak signals but very few dropped calls.

The new iPhone 5 just ends calls occasionally. It’s not a dropped call. It suddenly just ends a call as if it were never on one. Sometimes this is actually a feature.
