Zusammenfassung:This invention relates to business communication systems and, in particular, to message service system apparatus that provides a call transfer capability between a message service system (110) and any of the telephone station sets (TI00) and trunk circuits (TR1) of a telephone switching system (100). The business communication system provides a number of message service systems (voice mail (110), message center (120), etc.) and integrates the control of these message service systems so that a calling party can transfer an existing call connection between the message service system (110) and any telephone station set (T100), trunk circuit or other message service system (120) served by the business communication system.
