摘要:
A multimedia mail system utilizes an analog telephone network and interconnects processors at a voice mail center and a text mail center, and provides data/voice transmit/receive mode selectors between the analog telephone network and the paired voice mail center and text mail center and between the analog telephone network and paired voice mail terminal and text mail terminal so that voice and text data can be switched during communication to provide a consolidated voice mail/text mail communication system.
