Occasionally it becomes necessary to block a poorly operating node. This method makes it very easy to manage a blacklist with three simple Asterisk CLI commands:
Occasionally it becomes necessary to limit connections to your node. The blacklist is used block a poorly operating node or small number of nodes. The whitelist allows only listed notes to connect.
It's very easy to manage both list with these Asterisk CLI commands:
* database put blacklist 1998 "any comment"
* database put blacklist 1998 "any comment"
* database del blacklist 1998
* database del blacklist 1998
* database show blacklist
* database show blacklist
* database put whitelist 1000 "any comment"
* database del whitelist 1000
* database show whitelist
* database show
