Deploy E9-1-1 in Skype for Business Server 2015

 

Topic Last Modified: 2015-08-17

Deploy E9-1-1 in Skype for Business Server Enterprise Voice. Includes prerequisites and deployment process checklist.

Enhanced 9-1-1 (E9-1-1) is an emergency notification feature that associates the calling party’s telephone number with a civic or a street address. Using this information, the Public Safety Answering Point (PSAP) can immediately dispatch emergency services to the caller in distress.

To support E9-1-1, Skype for Business Server must be able to correctly associate a location with a client and to make sure that this information is used to route the emergency call to the nearest PSAP.

Before you deploy E9-1-1, you must already have deployed your Skype for Business Server internal servers, including a Central Management store, a Front End pool or a Standard Edition server. You must also deploy one or more Mediation Servers, either standalone or collocated with Front End Servers. In addition, an E9-1-1 deployment requires a SIP trunk to a qualified E9-1-1 service provider or an Emergency Location Identification Number (ELIN) gateway to your public switched telephone network (PSTN).

The following table provides an overview of the E9-1-1 deployment process.

 

Phase Steps Roles Deployment documentation

Configure voice usages, routes, and trunk configurations

  1. Create a new PSTN usage record. This is the same name that is used for the PSTN Usage setting in the location policy.

  2. Create or assign a voice route to the PSTN usage record created in the previous step and then point the gateway attribute to the E9-1-1 SIP trunk or ELIN gateway.

  3. For a SIP trunk E9-1-1 service provider, set the trunk that will be handling E9-1-1 calls over the SIP to pass PIDF-LO data by using the Set-CsTrunkConfiguration –EnablePIDFLOSupport cmdlet.

  4. Optionally, for a SIP trunk E9-1-1 service provider, create or assign a local PSTN route for calls that are not handled by the E9-1-1 service provider’s SIP trunk. This route will be used if the connection to the E9-1-1 service provider is not available. If supported by your E9-1-1 service provider, assign a trunk configuration rule to the gateway that translates the 911 dial string into the direct inward dialing (DID) number of the national/regional Emergency Call Response Center (ECRC).

Create location policies and assign them to users and subnets

  1. Review the global location policy.

  2. Create a location policy with a user-level scope; or, if the organization has more than one site with different emergency usages, create a location policy with a network-level scope.

  3. Assign the location policy to network sites.

  4. Add the appropriate subnets to the network site.

  5. (Optional) Assign the location policy to user policies.

Configure the location database

  1. Populate the database with a mapping of network elements to locations.

  2. For ELIN gateways, add the ELINs to the <CompanyName> column.

  3. Configure the connection to the E9-1-1 service provider for validating addresses.

  4. Validate the addresses with the E9-1-1 service provider.

  5. Publish the updated database.

  6. For ELIN gateways, upload the ELINs to your PSTN carrier's Automatic Location Identification (ALI) database.
