CER and CSF tracking

[TXG]

Does anyone happen to know if there is a way to restrict CER from tracking CSF clients?  We have a popup that notifies users to not dial 911 from Jabber, so it seems like a waste of licenses to have CER track the clients.

Thanks

You cannot.  A license is required for any endpoint that is capable of making a 911 call.  Preventing that in CUCM does not nullify the fact that the endpoint is still capable overall of 911 calls.

License Usage

An Emergency Responder license is of single type User and one license is required for each endpoint. Any endpoint capable of making an emergency call requires an Emergency Responder User License. For example, IP phones, analog phones, video endpoints, and clients all require an Emergency Responder User License.

Thanks Andrew.

Technically you can add the data subnets into CER as "do not track" and this will stop a license from being consumd by the CSF. But also, CIPC, and any other softphone on the data subnets.

Also, I see a lot of deployments where the CER license is roughly equal to the user count on CUCM, but with features like CSF, you really need to consider a CER license a device based license, despite it saying "CER User." My $0.02.
