If necessary, email messages are transformed to fax messages or read to the user over the phone. The Active Messenger is aware of which devices are available for each subscriber, which devices were used recently, and if a message was received and read by the user by exploiting back-channel information and by inferring from the users communication behavior over time. In summary, the Active Messenger Integrates mobile delivery devices like pagers, with conventional email reading systems. Makes filtering a process rather than a routing problem. Associates filtering rules to user locations.
Converts email messages to faxes and speech.
