I would think the first thing to do is contact your local telco. You
should work with them to determine who this is. They should be able to
figure out who is initiating this attack (ANI or otherwise). It could be
as harmless as someone having a misconfigured telemarketing system or a
fax spammer looking for places to send junk. But I would START with your
local telco.

Subject: War Dial on my PBX
My company's PBX system (Nortel Meridien) is getting hammered. All our
DIDs are getting hit. Aside from disabling trunk to trunk, what could I
do
to help mitigate this problem. Another office last year was hit and
through the voice mail system someone was able to make $25,000 worth of
calls in a day. This was another system though.
Any help is much appreciated.
