Call Back Verification

CBV, or Call Back Verification is a must-have for sysops concerned about security of their bulletin board system. Call Back Verification works by hanging up on a remote caller and calls them back at the number specified as their data line - thus verifying the phone number and in most cases, the caller.

  • Ability to work with ANY BBS software product.
  • Duplicate and bad phone number checking with option to automatically validate duplicate phone numbers.
  • Support to allow users to enter different phone number for callback. Sysop configurable.
  • Complete sysop logging.
  • Built-in support for multiple local area codes.
  • Completely external display files for sysop customization.
  • Dialing methods which allow you to configure how CBV should dial specific numbers to access dialing plans, dial area codes in special ways, dial outside lines on certain numbers, etc.
  • Random code word generation instructs CBV to pick a random code for the user and then asks for it upon successful callback. Can be used in place of the password checking feature.
  • Support for RemoteAccess BBS software's new text-password option.
  • FOSSIL specific support.
  • Added security settings for subscription days, group numbers, credit values and calls per day.
  • Smart long distance callback. If users number(s) are determined to be long distance and long distance callbacks aren't allowed, CBV will notify the user and abort.
  • Direct support for WWIV BBS, RemoteAccess, PowerBBS, and TriBBS is already available as well as any BBS software that utilizes EXITINFO.BBS info file, or read-back of the standard DOOR.SYS dropfile.
  • Split-screen, sysop to player chat mode
