This appears to be a network issue you have occurring. Sometimes there are issues with the network communicating between your phone and the tower. If it happened on every single call I would be worried. But the fact that it is an intermittent problem leads me to believe the issue lies with the network. The reason it most likely starts to work again after you restart your phone is because the phone is forced to search for a signal and re-communicate with the network thus solving the issue for the time being. There doesn't seem to be a work around for this. This is just a common problem as being a cellphone user in an overcrowded network.
