We are looking for a way to accurately determine the amount of time a caller spends on a call in freemium contact center. In call reports, Does 'Start Time' on a call directed to a queue equal the time the call was received by the PBX? Does 'Answer Time' equal the time the call is picked up by an agent? We aren't seeing a difference between these two elements in our reports. Is there a way to determine the length of time an agent spends with a caller compared to the length of time the caller spends total in the PBX when using this version of contact center?
