HELD Location Switching

How it works
Before the Emergency Call
• End-user devices are tracked through the Cisco Emergency Responder (CER) MAC Address, IP Subnet, or Wi-Fi access point methods, when on-premises.
• Organizations using Webex will have the ability to utilize HELD for setting user locations.
• Granular dispatchable location address information for both on-premises and off-premises users is validated and synchronized with 9Line by CER, then stored and ready to be assigned when a 911 call is made.
When an Emergency Call Occurs
• Cisco Emergency Responder will perform its standard operations of changing the calling party number and selecting the correct route pattern to send the call to 9Line.
• Cisco Unified Communications Manager will use the selected route pattern to route the call.
• The customer gateway (CUBE or other SBC) sends the 911 call over the top via the Internet, securely encrypted if desired, to the highly available, active-active, 9Line session border controllers.
• 9Line inserts metadata containing the address information set earlier by the user or the administrator.
• The call is presented to the responsible PSAP with the dynamic metadata information.
In Case of Disconnect
• The PSAP will attempt to callback the number CER has assigned for the emergency call. In the case of on-premises phones, this is the ELIN. For off-premises users, CER requires assigning a unique DID to the user. This callback occurs via the customer’s regular PSTN (PRI/SIP) service.
