Your voice phone number has been found to be in an invalid format. The BBS and call back verifier (CBV) need your phone number to be in a valid USA format. Unfortunately, the system allowed you to enter a number using a format other than that required. We ask that you please enter a valid USA-format phone number at the prompt. This should be your voice phone number where you can be reached by voice should the Sysop need to contact you. An Example of a valid USA format would be (416)579-3256 Thank you for your time.
