The pre-defined responses may be sent (i.e. are embedded) with the voice mail message to a recipient's mailbox so that when, the recipient opens the voice mail message the message is heard, and the, recipient is provided with a menu of pre-defined responses from which to choose. After listening to the pre-defined responses the recipient selects a, particular response which is then forwarded to the creator of the original voice, mail message.

Why it's free to use
- Filed October 27, 1997 and granted December 19, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 27, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 27, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
