The dBASE file DNA.NDX is an alphanumeric dBASE index file that lists any caller numbers that you wish to blacklist so that the system never answers a call from that number. This feature is only available when Caller ID (ANI) information is available before the call is answered and you are using a voice board which supports this.
The file must be created using:
PIN DNA C20
The entries in this file are either complete telephone numbers or one of the special codes 'O', 'P' or 'X'. Entering 'O' excludes out-of-area numbers for which caller information is not available. 'P' excludes private numbers for which caller data has been withheld. 'X' excludes all numbers if caller data is not supported from the line.
If and when the call is answered, the caller phone number data is made available in a system variable @ANI (automatic number information).
Default: all incoming calls are accepted.
