Step-by-step explanation:
When you phone for help, it's crucial to stay on the line with the dispatcher until you're asked to hang up. The dispatcher is trained to gather essential information and provide you with instructions to ensure the safety and effectiveness of the response. Remaining on the call also allows the dispatcher to update you on the status of the arriving help, such as an ambulance, and to keep them informed of any changes in the situation.
