Hi Jay,
 Unwelcome Communications procedure only work when you have the source numbers. It's hard to give the CTS provider ~10,000 source numbers ;) They are trying however to chase it up.  No it's not coming from a sip gateway. This equipment is not on the internet.

Matt.

There are methods for dealing with unwelcome or nuisance calls.
It's not always effective, but its worth a try.

If your calls fit the definition of an "UNWELCOME COMMUNICATIONS" you may be able to utilise http://www.commsalliance.com.au/Documents/all/codes/c525.

The OP may have a claim to this with 3000 calls within 4 hours.
Contact your CSP. /"C/CSPs must assist end users in receipt of unwelcome messages where it is reasonably possible to do so "/

They may only pass the complaint on to the originating carrier, but you might get lucky. The other thing I initially thought of when I saw this ( but it seems like its probably not the case after reading other peoples accounts ). Make sure your SIP equipment only accepts SIP from your SIP provider. Sometimes you find people scanning your network, doing this sort of thing.

Good luck !

Jay

    The volumes we are getting are stunning if it's not targeted at
    AAPT.  as it appears it's not from some of the on/off list
    responses. We have had over 3000 calls in the last 4 hours. This
    has been going on for almost 4 days.

        Hi Matt,

        We have seen multiple instances of this over the last couple
        of months to different number blocks.

        It's usually a Mandarin message claiming to be from the ATO.

        Have logged a few complaints on a few of them; have not got
        anywhere useful because each number is called "once" and
        doesn't meet the threshold for a nuisance claim.

        If any of my upstreams want to care though… I'm happy to
        provide more details… :) (nudge… nudge…)

        Andrew

            Here's some Friday fun.

            Are there any people with AAPT CTS that are receiving
            very high volumes (500 an hour)  of a Chinese language
            automated message. Numbers dialed in appear to be random
            within a routed ranges they also appear to be using
            random calling id's some start with 028009XX. Im told
            that the message says it's from the Chinese consulate and
            ask you to push zero.  I suspect they are trying to
            determine which numbers have Chinese language speakers
            answer for some later scam. But only appears to be on
            AAPT CTS. We have CTS with a few other carriers and
            seeing nothing on those inbound.

            Interested to see if others are receiving same.

            Matt.
