13.3.4.7. General Announcements with call to station and no answer 
- Has the COT parameter ABNA been set for the connecting line? (COT parameter IFR is optional)
- Are you sure that the COT parameter KNDI has NOT been set for the connecting line?
- Has the timer for "announcement with station no answer" been assigned an appropriate value? (CTIME: CP1, ANNDIAL)
- Is the announcement reason (ANNOHK) entered in the ANNTONE branch in the AMO-SYNCA?
- Have the correct entries been made in the announcement reason/announcement type table,
ANNMITR?
(SYNCA)
- For direct lines:
- For direct dialing to the a station user, the appropriate announcement types must be entered for the ANNOHK announcement reason in the ANNMITR table for the ITR number of the called station user.
- For callers who reach the station user via FWD/FNANS/FBSY, the appropriate announcement types must be entered for the ANNOHK announcement reason in the ANNMITR table for the ITR number of the forwarding station. However, this only works for forwarding stations in the same node as the announcement unit or in homogeneous OS4k networks, where the partner node can provide the ITR group information for the redirecting station. Otherwise, the ITR number of the called, busy station user applies.
- For transit lines:
In this case, the timer runs in the node with the exchange line interface (originating node).
- Is the synchronized announcement configured in the originating node?
- For direct dialing to the a station user, the appropriate announcement types must be entered for the ANNOHK announcement reason in the ANNMITR table for the ITR number of the calling exchange line.
- For callers who reach the station user via FWD/FNANS, the appropriate announcement type must be entered for the ANNOHK announcement reason in the ANNMITR table for the ITR number of the forwarding station. However, this only works for forwarding stations in the same node as the announcement unit (e.g. originating node). Otherwise, the ITR number of the exchange line applies.
