Direct access to a voice mail box hosted by a voice mail system (VMS) permits a requesting party to go directly to the voice mail box without first placing a call to the service subscriber who owns the voice mail box. Direct access can be enabled from call termination equipment such, as a dial-up directory service, or from a data network interface, such as a web page on a worldwide web server or a button embedded in an electronic mail message.

Why it's free to use
- Filed July 9, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 9, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 9, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
