1. A telephone system, comprising:
- a memory for storing user preference data, including duration of a timeout period;
a counter; and
a microcontroller for initializing the counter in response to an off-hook condition and, if a value of the counter equals the duration of the timeout period before detection of an on-hook condition, transitioning to the on-hook condition.

Abstract
Method and apparatus for providing accessibility features for a telephone is described. In one example, a telephone system includes a memory, a counter, and a microcontroller. The memory is configured to store user preference data, including duration of a timeout period. The microcontroller is configured to initialize the counter in response to an off-hook condition and, if a value of the counter equals the duration of the timeout period before detection of an on-hook condition, transition to the on-hook condition.

12. In a telephone system, a method comprising:
-
detecting an off-hook condition;
initializing a counter in response to the off-hook condition;
comparing a value of the counter with a duration of a timeout period;
monitoring for an on-hook condition; and
transitioning to the on-hook condition if the value of the counter equals the duration of the timeout period before the on-hook condition is detected. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
