| CALL_STATUS_BC | 0x0040 | Broadcast message telling the status of a call |
| CONN_STATUS_BC | 0x0041 | Broadcast message telling that a connection is established |
| DISCON_STATUS_BC | 0x0042 | Broadcast message telling that a connection is disconnected |
| EXT_FEATURE_BC | 0x0043 | Broadcast message when a directory number (feature 50) is dialed on a station |
| Q_ELEM_ADDED | 0x004B | Broadcast message. Reports that a mail message has been added to a station’s mail queue |
| Q_ELEM_REMOVED | 0x004C | Broadcast message. Reports that a mail message has been removed from a station’s mail queue |
| CONF_IS_ROOT | 0x007B | Broadcast message. Sender informs that it is root of conference |
| CONF_NOT_ROOT | 0x007C | Broadcast message. Sender informs that it is no longer root of conference |
Message example
The messages below are broadcast messages transmitted from the AlphaCom on the AlphaCom Data Protocol when a call is initiated by the command: $CALL L8002 L8009
