There's nothing (that I know of) wrong with allowing tf.voipmich.com to handle toll-free calls instead of FWD. I also set up entries to pass toll-free calls to FWD also because my default provider (Gizmo Project) used to bill for toll-free calls. I then discovered they were being routed to tf.voipmich.com instead due to ENUM, but concluded this was just fine. Should tf.voipmich.com stop providing this service (and nobody else picks it up), then the ENUM lookups will fail and my toll-free calls will go to FWD as originally intended. I think the current situation is best of all worlds.
