Try adding a '1' in front of the number if you are not already doing that.
If the call completes even with the message, then just ignore the message. It should clear itself up.
If the call does not complete try toggling into airplane mode, or perform a reset of your network settings.
Perform a Reset of your device's Network Settings.
