I think that even without Verizon now (if that's even the 5% in question), they will eventually agree to a contract. It might take GoIP Global generating more revenue so they can pay more, or Verizon missing out on profits, or both. I believe that the issue is more of how much it delays expected profits. Maybe it's only a week or two weeks or a couple months.
Also, GoIP Global can setup an 800 number to provide the exact same functionality, but without the convenience of a short code. In this situation, it would be a good band-aid option to any roadblocks.
