I had a similar experience earlier this week, and was able to fix it.

I would get a phone call, the phone would ring once, then show up as a missed call. The person calling me would not hear any ringing, and would never get voice mail.

I called Verizon, and they were able to fix the problem. The rep told me that the touch does not have an ESN, it has some other sort of thing (forgive me, but I can't remember what she called it...she said it was more advanced than an ESN) that "falls off the network from time to time". After about 2 minutes on the line with her, it was fixed.

You are not describing the exact same problem, but you may want to speak with tech support to find out.
