What is a telematics call similar to a 911 open call called?

A telematics call similar to a 911 open call is referred to as an Emergency Button activation, No voice call. This type of call typically involves the automatic transmission of emergency signals from a vehicle to a Public Safety Answering Point (PSAP) when an emergency occurs, such as in the event of a crash. The system may activate a button that sends location and vehicle information to the telecommunicator without the need for verbal communication.

This classification is essential because it alerts dispatchers to an incident where immediate assistance may be required, even if the caller is unable to speak due to the nature of the emergency. The system is designed for situations where the person in need of help cannot communicate verbally, allowing for timely and potentially life-saving intervention by emergency services. The focus on response regardless of whether a voice call has been established highlights the role of such telematics systems in modern emergency response protocols.
