Call cannot be completed as dialed

Why do I keep getting "your call cannot be completed as dialed please check your....." but then it ends up going through. Really really annoying considering this is brand new account for me.

That could be due to an error with your account, or a setting in your phone/contacts, or a network outage, or an issue on the end of the party you are trying to reach
