ABSTRACT:
An end user terminal (EUT), e.g., such as mobile terminal (MT) (20), is provided for connecting with an incoming call received over a communications network (A). Suitably, the EUT includes an alerting function and/or equipment that provides perceivable alerting in response to an incoming call attempting to connect with the EUT over the communications network (A). An alert sensor (AS) (22) detects an alerting status of the EUT, which is then communicated over the communications network (A), e.g., back to the calling EUT50.
