[AusNOG] High number of inbound automated Chinese language calls on AAPT CTS

[jay binks]

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
