A mail delivery service that allows users of a networked call processing system to listen to messages that are being left to their mailbox in real time. Improvements applied to this invention allow full control of both the message and the call that is leaving the message to more effectively screen the call and enhance follow up communication with the calling party. The system further enables users to forward messages in real-time to other users within the telephone network, conference in other users, and discuss the message as the call is being recorded by a voicemail system. Other monitoring options are provided whereby the caller may, for example, add a textual notation to a call, terminate the call, and apply a custom configured hot rule to manage the call in accordance with the user's wishes.
