A multimode service system processes calls routed to it by a digital switch in a telecommunications system wherein choices are selectable by the user. Calls are processed by automatically determining the mode of communication utilized by the calling party and communicating with the calling party utilizing the calling party's communication mode to obtain information needed to route the call or implement user selectable features. A reply from the user provides information which determines feature selection or a call routing path. The multimode servicesystem transmits a signal to the telecommunications system which defines the feature or path selection based on the reply from the user.

Why it's free to use
- Filed May 12, 1993 and granted September 16, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 12, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 12, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
