iphone 4s not calling - common problem?

[iNeedToDoHw]

I got the iphone4s once it came out and I've been having some issues with calling. 4 out of 10 times I dial a number, it doesn't ring. I have to either manually end the call or wait for it the phone to automatically end the call to redial. I can hear the phone ringing the the 2nd time i dial.

What could be the source of the problem? I turn on wifi the whole time, could that be the problem?

who's your carrier?

What's you're signal like when you make these calls?

i'm on verizon and the signal is very good. it's annoying when i dial someone and realize later that i have to end the call and redial to get it to work again.
