I have a Definity G3si R8 and an Intuity Audix voicemail. One of my users is concerned over the number of crank/harassing calls left in their voicemail. The calls never ring at the handset only a message is left in the voicemail. I do not have a call accounting package installed on the system. Is their a way I can track and provide a report of all activity on this station with the purpose of discovering the source of the messages? Please advise.
