Personally, I use the EC500 method. I have 10 allocated just for call block purposes. Use EC500, and it's "one and done". Use the inc-call-treatment method, and I have to put in an entry for each DID. Too much work for me.
I completely agree with David, I would like to see an ANI denial list from Avaya.

You can have it all. You just can't have it all at once.
