Using BLACKLIST without affect my call abandonment rate


I am using the BLACKLIST function to avoid incoming calls from know-fake clients in my Asterisk 1.8 server.
The blocking is working fine, I hangup the call if the caller ID is in the blacklist database.
The thing is my “blocking” is to hangup the call so it is adding a line to the CDR with the application “hangup” and the disposition “NO ANSWER”.
The abandon rate is being affected by this disposition.
What would be a clean to avoid this?

Thank you in advance


Thank you

That was exactly what I was looking for.
