NG911 Emergency Call Routing Function

As part of the West Advanced 9-1-1 (A9-1-1®) i3 Routing packages, the A9-1-1 Emergency Call Routing Function (ECRF) offers complete NENA i3capabilities, but not all PSAPs are positioned to move directly to a fullA9-1-1 i3 Routing solution. PSAPs that have purchased the A9-1-1 IP Selective Routing package have a low cost option to utilize key NENA i3 functionality to route 9-1-1 calls using the A9-1-1 ECRF.
