8.3.2. Assignment of the Messenger Facility 
The messenger facility can be assigned to one or more terminals in
an executive/secretary system with the AMO ZIEL or a procedure at the
terminal. Allocating a messenger to several executive/secretary systems
is only feasible if the secretary terminals are in the same office, since
it is not possible to establish who has rung. The messenger call is initiated
with the messenger button. Prior to deletion the facility must be released
from its allocation to executives and secretaries. These allocations
are interrogated with the AMO ZIEL. The messenger code must always be
3 digits long so it can be recognized as messenger number by the OpenScape
4000 set.

- Assign the messenger to the executive telephone
AD-ZIEL:TYPE=MSGR,SRCNO=number,DESTNOM=number;
