Agenda Quick Intro What is E9-1-1? How does Lync Support E9-1-1? High Level Considerations Technical Deployment Considerations Q/A
What is E9-1-1? cation Based Emergency Routing LYNC USER GROUP
hat is E9-1-1? Emergency Dispatch Feature Meets requirements for providing more detailed location information for emergency calls. rth America has strict requirements on providing this information. Use location information to route to the proper Public Safety Answering Point (PSAP) pulate using IP network information, or physical port information for traditional systems.
w does Traditional E9-1-1 Work? When 911 is called, caller is routed to whatever PSAP has been designated by the telephony company. Provider maintains database that contains Automatic Number Identification(ANI) formation. AP maps ANI to Emergency Response Location (ERL). M PBX must match physical location to extension using ANI and ELIN – hard to maintain. -PBX makes the problem harder because IP endpoints can roam easier. ypically you need a separate piece of hardware to maintain location formation that is mapped to switch ports.
w Does Lync Support E9-1-1? ync can be configured to include location information when making emergency calls. cation database contains configured locations. User signs on and requests location information if configured. Provides exact location such as building, floor, conference room to the PSAP. pports roaming Lync users, inside or outside the network. pported in the United States, but can be used anywhere for the same benefits.
High Level Considerations
ntify Your Requirements
fine the Scope What areas of your enterprise need to be enabled for E9-1-1? How will you deploy to your branch sites? Will you enable 9-1-1 for remote users? Do you want to provide emergency call routing outside of the US?
w Will You Enable Users? Do you plan on enabling all users, or limiting support to specific geographic areas of the enterprise? Do you plan on enabling individual users or devices through a user policy? When clients roam outside the network or are connecting from an undefined subnet, should the clients still be enabled for E9-1-1?
w Will You Manage Locations? Do you already have a database populated from another system? How will you maintain and update the location database? Will you use an SNMP application to match Lync client MAC addresses to port and switch identifiers?
an For The User Experience How will not having a location defined effect users calling 911? Should users be prompted to enter a location when one is not found LIS?
an Your Connectivity Should you deploy the SIP trunk over a dedicated leased or a shared internet connection? your E9-1-1 deployment designed for disaster tolerance? Should you deploy a separate SIP trunk for each branch office? Call Admission Control deployed?
hat About Your Security Desk? Do you want the security desk to be notified when there is an emergency call? Do you want to conference the security desk in on each emergency call?
Technical Deployment Considerations
hat Network Elements are Used? Wireless access point (WAP) Basic Service Set entification (BSSID) addresses (Layer 2) LLDP switch port IDs (Layer 2) LLDP switch chassis IDs (Layer 2) Subnets (Layer 3) Client MAC addresses (Layer 2)
portant Configuration T asks High-Level Steps Create a dedicated PSTN usage for 911 Create a dedicated Voice Route for 911 Enable PID-FLO Support on your Trunk (Set-CSPSTNTunkConfiguration – EnablePIDFLOSupport $True) Configure your Location Policies Populate Location Information Validate Addresses Location Policy Assignment By Subnet- allow specific locations to be configured Users- allows users outside of offices to be configured
w a Locations are Populated Lync Servers E911 Provider Call Center Mediation SBC SIP TRUNK LIS DB Front End 2 1 Validation DB 3 nc Client Admin 1. First the admin must populate the location database and enable users and or subnets for e911. 2. The address information is then validated against the MSAG DB through the 911 provider. 3. Then the provider can send back the status of the addresses, and let the admin know if any are invalid. Only at this point, can the addresses be used for 911 calls.
w a Locations are Acquired Lync Servers E911 Provider Call Center Mediation SBC SIP TRUNK LIS DB Front End 1 2 Validation DB 3 4 nc Client 1. When the client registers it will send its current location information. This will be in any of the formats from before, like subnet, ssid etc. 2. The front end will then return a LIS URI to contact for a location query and policies for 911, assuming that user, or their current location is enabled for e911. 3. The client will then send the subnet information over to the LIS database 4. The lis database will look up the subnet information, and return all of the details in a SIP message.
w 911 Calls are Routed Lync Servers E911 Provider Mediation Call Center SBC SIP 2 TRUNK LIS DB Front End 2 1 Validation DB 1. The client will dial 911. Because this was identified as the emergency 3 dial string that was configured by the administrator, this will automatically nc Client classify this as an emergency call and include the location information in the invite. PSAP 2. The E911 call will then be routed through the designated mediation server, over the sip trunk to the provider. 3. The provider will route and connect to the appropriate PSAP. If the location was manually entered or not valid, the user would be connected with an operator to validate the address before forwarding to the PSAP.
