In the “ANI blacklist” you can define caller IDs or area codes, which will not be routed to the defined routing destination / routing plan. You can choose for these caller-IDs between following options:
a) Reject call (the caller gets automatically a busy signal/message and the call will be terminated)
b) Announcement (an announcement will be played back to the respective caller and the call will be terminated)
c) “Named Routingplan“ (The call of the respective caller will be forwarded to a pre-defined “named-routingplan”.
