Core IssueThere is probably a problem with the configuration of your standby Cisco Emergency Responder server.
ResolutionIf you have only configured a primary Cisco Emergency Responder server, install and configure a standby Cisco Emergency Responder server. If CPU utilization on the primary server reaches one hundred percent, the Cisco Emergency Responder cannot handle emergency calls. In this case, the standby server handles the calls.
To resolve this issue, perform these steps:
- Check the route point configuration for the standby server.
- Ensure that the emergency call route point's call forward settings are configured to forward calls to this number.
For information on the Cisco CallManager configuration, refer to the Creating the Emergency Call Route Points section of Configuring Cisco CallManager for Emergency Responder.
