Programming Procedures
Principal User for Personal Line
Use this procedure to assign or remove one telephone as principal user for a
personal line. When a telephone with Remote Call Forwarding activated is
assigned as principal user, calls received on the personal line are forwarded to
an outside telephone number. In addition, calls received on that line are sent to
that telephone's individual and/or Group Coverage receivers unless the
Personal Line button is set to No Ring.
The principal user assignment must be removed before the trunk can be
removed from a button on the telephone.
When no principal user is assigned for a personal line, calls received on the
personal line are not forwarded to outside telephone numbers and calls
received on the personal line follow the Coverage patterns for all users who
share the line.
