One of my customer is running a cluster of CCM 6.x. All the 911 calls are routed through the Analog lines /FXO installed on the routers. Everything is working fine.
Customer has also got a CER server and wants to use that just for notification purpose. No ELIN , NO ERL .
If someone dial 911 then call should use the analog lines and should show the notification info via email / phone or web browser.
What is the minimum config needed for this setup ?
