Study Notes

TopicExplanation
E911Enhanced 911 — automatically transmits the caller's address and telephone number to the emergency dispatcher when 911 is dialed; no need for the caller to state their location
Traditional 911Caller must identify their location manually
PSAPPublic Safety Answering Point — the regional emergency services dispatch center that receives 911 calls
Kari's LawUS federal law (effective February 16, 2018) — requires multi-line telephone systems (MLTS) to: (1) allow direct 911 dialing without a prefix, and (2) send a notification to a designated person when 911 is dialed
MLTSMulti-Line Telephone System — any phone system with multiple lines; contact centers are MLTS operators
Location DetailsConfiguration in Genesys Cloud that stores a physical location address — used for E911 routing and Kari's Law notifications
HELDHTTP-Enabled Location Delivery — protocol that allows Poly phones to query a Location Information Server (LIS) for their precise network-based location at call time
LISLocation Information Service — a server that maps network location data (IP, MAC) to a civic address for E911 purposes

Kari's Law Requirements (US Only)

Kari's Law applies to Genesys Cloud Voice customers in the United States.

RequirementGenesys Cloud Voice Behavior
Direct 911 dialing (no prefix)Automatically satisfied — no customer action required

How to Configure Kari's Law Compliance (Genesys Cloud Voice)

  1. Contact Genesys Cloud Voice support
  2. Provide the following:
    • Full location address (US addresses only — Canadian addresses do not support notification)
    • Email addresses or email-as-text addresses to notify when 911 is dialed (e.g., [email protected], [email protected])

Notification is triggered based on the physical location address configured in Location Details.


Configuring Emergency Numbers in Sites

For all telephony options, emergency numbers are configured at the site level.

StepPath
Open AdminAdmin → Telephony → Sites
Select siteChoose the appropriate site
Open Number Plans tabClick Number Plans
Select Emergency planClick on the Emergency number plan in the list
Enter emergency numberType the emergency services number (e.g., 911 for the US)
Kari's Law noteUS users must not alter the 911 number with a prefix or any other modification

Warning: Do not assign an emergency number plan to a BYOC trunk unless you have verified with your carrier that they provide emergency services and that the carrier has the correct location for your phone numbers.


BYOC and Emergency Services

Genesys Cloud Voice includes built-in E911 support. BYOC customers must arrange E911 separately:

OptionE911 Approach
Genesys Cloud VoiceE911 included — configured through Location Details and Kari's Law setup with Genesys support
BYOC CloudMust check with your carrier — carrier must support E911 for your numbers and locations
BYOC PremisesMust check with your carrier — same requirement; also need to verify site-level number plan configuration

For BYOC E911 setup: Admin → Telephony → Trunks → BYOC trunk → configure as directed by your carrier

Reference article: "Set up emergency services with BYOC" in the Genesys Cloud Resource Center.


HELD — HTTP-Enabled Location Delivery (Poly Phones)

HELD allows Poly phones to retrieve their precise network location from a LIS server and include it in the SIP INVITE when a 911 call is placed, enabling more accurate emergency routing.

Supported phones: Poly VVX, Poly CCX, Poly Edge E

HELD Configuration Steps

StepWhere
1. Enable Location Conveyance on trunkAdmin → Telephony → Trunks → External Trunks → [trunk] → General → Outbound → check Location Conveyance
2. Enter Emergency Routing Service Account IDFrom your emergency service provider (or token ID if token authentication is required)
3. Enter Location Information Server URLURL to send HELD requests to
4. Enable HELD in phone Base SettingsAdmin → Telephony → Phone Management → Base Settings → [Poly base settings] → enable HELD

How E911 Works — Genesys Cloud Voice

Agent dials 911
        ↓
Genesys Cloud Voice looks up the physical location address associated with the agent's number / location
        ↓
Call routed to appropriate PSAP for that address
        ↓
PSAP receives caller's address and telephone number automatically (E911)
        ↓
Kari's Law notification sent to designated email/SMS addresses

Locations Configuration

Physical location addresses are configured in: Admin → Telephony → Locations

Each location stores:

  • Full physical street address
  • Used by E911 routing (Genesys Cloud Voice)
  • Used by Kari's Law notification configuration
  • Assigned to sites, phones, or users as appropriate

E911 for Remote Workers

Remote workers present a challenge because their physical location is not fixed. Genesys Cloud Voice provides E911 configuration options for remote workers — the physical location address must be kept current for accurate PSAP routing.

ConsiderationDetail
Accurate location data requiredInaccurate location may route the 911 call to the wrong PSAP — potentially causing delays
National fallbackIf E911 cannot locate the caller, the call may route to a national emergency response service (less accurate, slower)
Remote workersMust have their location updated when they change physical locations
