The blank stare of CUE…..sometimes.

Those that have configured CUE know that it sometimes responds erratically to changes.  For example, when the IP address is changed.  Often times you will find phones dialing into the pilot number and disconnecting quickly or simply hearing dead air.  Usually this means you need a reset of the CUE module, but I have witnessed situations where it has required two reloads of the module.  The best command I have found to help isolate the problem is the “show call active voice” command.  It will show you all the call legs as well as the target/destination IP addressing for the voip legs.  This information can easily help you determine what IP address CME or CM is using when accessing the CUE module.  Make sure you keep the “dead air” call up to CUE when you issue this command otherwise you will not see the desired information.
