I have an ext. programmed as SCR 2500. This SCR 2500 has five rollovers (SCR 2550, 2551, 2552, 2553, 2554). There are six people who have all six of these SCR keys on their phone. My manager wants to track how long calls are waiting before they're answered by any of these individuals, how many calls aren't getting answered at all and going to voicemail instead, etc. I think the only way to check this info is to make 2500 and ACD queue and make all the people who answer it ACD agents. But someone told me to look at internal CDR. I don't think CDR will help at all. Please advise. thank you
