he action blacklist url HTTP request is triggered when a call is received. If the HTTP server of the configured url answers with 200 OK, then the caller is processed as remotely blacklisted and the phone silently rejects the call. In case the server answers with an error, the call is accepted and the phone is ringing. In case it takes too long for the answer, the call should be accepted. This timeout can be configured with the setting remote_blacklist_action_timer.
The blacklisting can be done via an Action URL, e.g.:
action_blacklist_url=http://myserver.com/blacklisted?caller=$remote
Action URL Settings - Action URL Settings (Section): Check for blacklisting
