Hello, I'm trying to add EWT to a script, once the call reaches the queue they hear:" your estimated waiting time is 1 minute" and then:"we are experiencing some system problem" error message. What I did in the "Select Resource “under the Queue I add "Get Reporting Statistic" with the setting Expected waiting time and CSQ IPCC Express. Also I placed a "Switch “tag for the AVG waiting time in minute  and I configure 1 to 10 with .wav file for each minute. Any suggestion? I can add the script if necessary. the software is UCCX 5 enhanced.  thanks in advance.
