What technology will facilitate automatic re-routing of 9-1-1 calls?

The Emergency Services IP Network (ESInet) is designed specifically to improve the efficiency and reliability of emergency services communications, including the automatic re-routing of 9-1-1 calls. This IP-based network enables better handling of emergency calls by allowing diverse communication methods, such as voice, text, and video, to be integrated into a unified system.

One of the key features of ESInet is its ability to intelligently route calls based on location, network conditions, and resource availability. This facilitates quicker and more effective connections between callers and the appropriate emergency responders, even in cases where a caller might be in an area outside their usual jurisdiction or mobile network.

In contrast, while the other options play important roles in communication, they do not specifically focus on or have the advanced capabilities required for the automatic re-routing of 9-1-1 calls. The Wireless Communication Network supports mobile communications but lacks the intelligent routing features of ESInet. The Global Positioning System provides location information that can be essential for dispatch but does not address routing itself. Standard PSTN protocols are part of traditional telephony systems that might not support the modern needs of emergency services and lack the flexibility and robustness of an IP-based network like ESInet.
