This section describes the requirements to enable Communication Manager to send SNMP inform messages to the Emergency Location Management Solution for non-SIP phones. For SIP phones, you must configure the Emergency Location Management Solution as an ELIN server with Session Manager. For more information, see the Emergency call routing for H.323 visiting users section.
Requirements are as follows:
  • In the Crisis Alert System Parameters screen, in the SNMP Inform to Notify Adjunct When DCP and H.323 Stations Go In-Service field, type y.
    • Communication Manager helps the Emergency Location Management Solution to track which endpoints are in service so that if an emergency call is placed, Emergency Location Management Solution can identify the caller’s location.
    • The Emergency Location Management Solution gets equivalent registration information from Session Manager when the Emergency Location Management Solution is configured as an ELIN server.
  • In the Crisis Alert System Parameters screen, in the SNMP Inform to Notify Adjunct When SIP Station Dials Emergency Call field, type y.
    Communication Manager sends inform traps to SNMP receiver when a SIP station places an emergency call.
    Note:
    Do not enable this field if Session Manager is handling emergency call logging to Emergency Location Management Solution.
  • In the FP Traps screen, set the Notification field to Inform for SNMP v3.
    You can access the FP Traps screen from the Communication Manager System Management Interface (SMI).
  • Configure Communication Manager to allow users to dial 911. 911 must be configured with call type alrt on the ARS Analysis screen to trigger the SNMP inform from analog, DCP, and H.323 endpoints.
    • For SIP endpoints, the Emergency Location Management Solution depends on the messages it gets from Session Manager. You must disable the second parameter at the bottom of Crisis Alert System Parameters screen.
    • Note that while 911 is the most common emergency number, the steps above work for any number configured on the ARS Analysis screen with the call type alrt.
