We have recently changed our network to EF QoS. To have this take affect I need to change the QoS settings in the enterprise parameters of the CUCM (Version 8.0) We currently have the default set (CS3):
CallManager to DeviceInterface : This parameter specifies the Differentiated Service Code Point (DSCP) IP classification for protocol control interfaces that are used in CiscoCallManager-to-device communications. Note: You must restart CiscoCallManager servers and associated devices for this parameter ... Restart the CiscoCallManager service and associated devices for the parameter change to take effect.
Am I reading this correctly that all CUCM servers must be restarted and all of the telephone sets as well? A second related question is that we have 7940s to 7962s (a couple of 7970s as well), is there any of the older sets and firmware that will not support EF?
