The voicemail system (Call Pilot ) has a record call feature. generally, the feature is disabled. You need to enable the feature in class of service. I would suggest also changing the message length parameter for the class of service - because the recorded call is stored as a message. If your messgae length is set to 3 minutes, that is the amount of time the call will be recorded too. Once you have enabled call record, users can access by dialing Feature 989.
