Cisco Emergency Responder: When Your IP Phones Do Not Show Up In CER
I experienced this in the beginning when I started adding phones. I was wondering why CER didn't see the phones that I would add to a switch in my test lab. But if you think about it, how would it know about the phones? The only time CER is going to know about these new phones is when they actually make a call to 911. The call first goes to the CUCM CTI route point. Then it gets forwarded to CER. That is when CER finds out about that phone. So I guess that makes sense. Any other call goes to CUCM and out the gateway.
