Emergency Responder (E911) colocation?

kardos420 · ‎07-22-2010

I have a client that has a cluster of Call Managers in a european country and would like to use that cluster for an office in Vermont USA and remove a local call manager there. This vermont location currently uses an Emergency Responder server for Enhanced 911 services.

Does any one see any issues using the E911 server across a T1 MPLS circuit.? Does the E911 server need to be colocated with the cluster? Are there bandwidth and latency requirements across the WAN?

Are there any other issues you can foresee having the E911 server there? Will E911 work with SRST in a failure situation?

Many customer use CER for multiple locations within a CUCM cluster. You should be able to do this, as for the configuration with SRST, I am not sure. Since one of the major functions of CER is to identify phones in their physical locations you should be able to configure it such that all emergency calls in the Vermont location would egress their local GW's.

You may wish to address the CER documentation to verify it meets your needs. This documentation can be found at the link below:
