This setting allows the company to decide what options the CSR has in regards to recording the phone call.  There are four options:

1. Yes, Always Record
2. Yes, but allow CSR to turn off
3. No, but allow CSR to turn on
4. No, never record

Options are 1 and 4 are straight forward - either the calls will always be recorded in its entirety or not recorded with no ability to record the call mid-call.

With option 2, the recording will automatically start upon the call being answered.  Then, the CSR will have the ability to pause or stop the recording.  If paused, the recording can resume.

With option 3, the call will not be initially recorded.  However, the CSR can then elect to start recording the call at any point thereafter.  Once the call is recording it can be paused or stopped again.
