Allowing users an option for being removed from the call list

[BiggerE]

Just started evaluating this product.  I was wondering is there away to allow someone receiving a call to remove themselves from the call list?

Example:  Hi this is X I'm calling to let you know X.  If you want do not want to receive future calls please press 9.

Is it possible?  Is there a resource you could point me towards to figure it out?

You can add them to a black list automatically.
First you crete a campaign, and add to it a blacklist (maybe empty).
You have them press a key or something that ends the call in a specific extended status, eg "NOCALL"
You then add a Disposition Rules so that numbers ending in ext status "NOCALL" are added to your blacklist.
