We have purchased Cisco Emergency Responder for our campuses Cisco phone network, however we are unsure if it will be able to handle what we need. Every phone has a DID, so we do not need CER for the Callback features, more than anything we would like to use it to track phone locations based on the switch port they are plugged into. We want CER to send out this location information whenever a emergency call Is made. We are wondering if CER will be able to handle the large amount of Emergency response locations, if it is only being used for this purpose and not the extension management portion? Does anyone have any experience with this.
