HELD Location Switching
Users with Webex registered to CUCM have the ability to utilize automatic location switching with HELD.
No DID's Required
Customers are not required to purchase DID numbers since the 9Line DID Pooling™ feature can keep CER in place and swap the real DID's from ELIN configurations.
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.
