Pro Tips

  • Always test it by calling in.

  • Choose the right mode:

    • Unconditional (*72) ensures every call is answered by us.

    • Conditional (*92 / *90) lets you catch calls only when you’re unavailable.

  • Remote disabling: If you’re traveling, you can turn it off via the portal or by dialing disable codes (*73, 93, 91).

  • Verify long-distance settings: Portal entries and dial codes may require “1” + area code for off-net routing.
