The Nortel Norstar Voice Mail Interface (VMI) allows connection of a third party stand alone auto-attendant or voice mail system to a Norstar system.
This interface provides the basics of integration:
forward to personal greeting
return to operator
message notification

3x8 DR5.1
6x16 DR2 or higher
