Abstract: A communication device having a display interface coupled to a controller configured to determine a status of messages received, to present a list of message indicators on the display interface, and to indicate the status of each message by presenting a corresponding message indicator with a textual character having a size that is based on the status of the corresponding message. The message status may be, among other characteristics, the priority or age of the message as determined by the controller.

Abstract: A method and apparatus is capable of detecting the presence of a non-linear echo path as well as transitions from non-linear echo path to linear echo path and vice versa. Additionally, when non-linear echo path is detected, the echo canceller (12) is configured to follow a prescribed logic routine that combats possible echo leak-through as a result of compromised cancellation due to non-linearity. This prescribed logic routine affords the echo canceller (12) protection against non-linear echo path by preserving an already converged state of the echo canceller (12) from possible divergence due to the occurrence of non-linearity in the echo path and thereby prevents echo leak-through that would occur due to divergence of the echo canceller (12).
