7.3.1.2 PSAP Does Not Receive Accurate Information
Follow these steps to verify, review, and confirm the configuration in the System
Administrator tool when the 911 call works, but the Public Safety Answering Points
(PSAP) does not receive accurate location information:
1. Verify the information configured in the NG911 provider's portal (this the customer's/
VAR responsibility) such as:
• ERLS - Emergency Routing Locations
• Location's name, house, street, city, county, state/province, postal code and so on.
• Subscribers
• Valid 10-digit DID for callbacks
• Any other relevant information that needs to be sent to the PSAP (this information is
not stored in the MIVB)
2. Review the NG911 provider's portal, which can display a history of calls from which
you can select a specific call, and see further details.
• RedSky - Monitoring -> Call History
• You can view a summary of the location information, and by clicking the "sip
handset" icon, bring up the SIP Header information. From there you can
determine if MiVB sent the right information (based on the device that is calling),
and/or the location information that Redsky looked up.
3. Confirm that the MiVB is configured properly to send the relevant information to the
NG911 provider:
• DID and CPN Substitution - configure per device or location that has the ability to
make Emergency Calls.
• SIP Peer Profile - configure a SIP Peer Profile dedicated to signaling with the
NG911 provider.
• SIP Devices Capabilities - configure SIP devices to provide location information.
• Class of Service - configure a COS for devices that will use the MyE911 Application
from the NG911 provider.
7.3.1.3 Gathering Information
If both the NG911 provider's portal information and the MiVB appear to be configured
correctly, gather the following information:
