E911 Anywhere®
Components and Architecture
There are two key components to E911 Anywhere®: a Web-based administration portal that administrators use to update their location records and the E911 Anywhere® voice positioning center (VPC) that validates location records, accepts 911 calls and routes 911 calls.
Web Administration Portal
When you sign up for the E911 Anywhere®, you are given login credentials to the Web administration portal, where you can administer the locations of all the phones on your network. You can upload a simple CSV file and make batch updates, or you can make individual changes to your phone locations. Once locations are uploaded, they are validated for accuracy.
The VPC accepts, validates and stores locations until they are needed to process a 911 call. When a 911 call is made the IP call server sends the 911 call over an IP broadband connection to the session border controller at the VPC. The VPC analyzes the calling TN (or SIP URI), retrieves the location and routes the 911 call to the correct PSAP. The VPC also forwards the location record to the PSAP.
