We route based on CLID to a queue that plays music for 5 minutes then plays. "You are now 975'th in the queue please hold" and the goes back to music. A recording is made of the snippet where it says how far they are in the queue and is emailed to the helpdesk for comedic value.

Faxes, when they answer a call are silent until they hear the tone from the 
calling fax.
A lot of the software that drives outbound calls will listen for silence on the 
far end so they don’t connect a human to a fax machine and waste time on their 
outbound call centre.

If you get a call from a number you don’t recognise, be silent when you answer. 
Mute if possible. A lot of the time your number will be marked as a fax machine 
and they’ll stop calling.

So, rather than have no answer as per below, route it to something that answers 
(costs them money to complete the call) and is silent to pretend to be a fax 
machine.

Not sure how your PBX is setup, but in the environments I've worked with I've 
avoided using default call routing on unallocated DID numbers back to the main 
number. I've found that a fair few of the scam callers dial through the full 
DID range. Doesn't stop the calls but can somewhat reduce the calls from them.

    Some of them are clearly invalid, I have examples like 07 6539 5789 and
    08 0804 4878 which are not assigned in the numbering plan

Doesn’t the subscriber handle it by complaining to ACMA? The Spam Act has to be 
worth something, right?
(if you block the number somewhere else, you’re just going to create a headache

scammer has moved on. It needs to be dealt with at the source, and that’s not 
exactly something you can do…)

What's the best way to handle these? In November we got a lot of calls
with random caller IDs, and I was gathering logs to open a case with our
carrier per the Comms Alliance CUSTOMER PROCESS –HANDLING OF LIFE
THREATENING AND UNWELCOME COMMUNICATIONS but by the time I was ready to,
they'd stopped.

Obviously that process is fairly weak sauce, particularly if you read the
actual code which allows for no action if the supplier is unable to
identify the source of the communication, but I was at a loss to find any
other process to try and stop the calls.

      Can every provider check their records to see if they are hosting

      This number is being used to scam / spam and the number should be 
terminated as soon as possible
