What does phase 0 refer to in call delivery?

Phase 0 in call delivery specifically refers to the process of delivering the call to any Public Safety Answering Point (PSAP). This initial phase is crucial because it establishes the primary connection between the caller and the emergency response system. It is the point where the call is routed to an appropriate PSAP based on factors such as caller location and the nature of the emergency.

Understanding this concept is essential for dispatchers, as it impacts how quickly and effectively emergency services can respond. When a call is delivered to a PSAP, the dispatcher can then take the necessary steps to assess the situation and dispatch resources accordingly. This foundational step is critical since it sets the stage for all subsequent actions related to emergency response.

The other choices relate to different aspects of call processing and management but do not specifically define what phase 0 entails in the context of call delivery to emergency services.
