How it works

Horizon Mobility® for Microsoft Teams is a cloud-based 911 solution that works with our softphone client to discover the location of the phone and route the call to the correct PSAP across the United States. SPS can be integrated via our API, or a branded portal.


MyE911 client performs network discovery (ND)

  • ND Information is sent to Horizon Mobility® Cloud
  • If this is a known location, User location set in Horizon Mobility® cloud
  • If user location is unknown, User prompted for location/address and sent to Mobility cloud
1b.Microsoft Teams Client performs location discovery.
2.User dials 9-1-1 with their Teams client


3.SIP Invite for the 911 call is sent to customer’s on-prem SBC containing PIDF-LO (civic address and/or geo)
4.Server sends 911 call to Horizon Mobility® via SIP including the PIDF-LO
5.Horizon Mobility® receives the 911 call and intelligently determines the most accurate location whether provided by MyE911® or Microsoft Teams Client, and routes the 911 call to the appropriate PSAP along with user location
