Calling restrictions for international traffic terminating to Australia

Due to strict spam monitoring and controls on communications terminating to Australia, calls with an invalid Automatic Number Identification (ANI) have a high likelihood of being blocked. This industry requirement isn’t specific to Bandwidth and impacts all international traffic terminating to Australia. We’re working closely with our partners in Australia to keep up with the latest updates to ensure that we can provide you with stable, quality services for outbound calls to Australia.

Note: The ANI must be ten digits and follow the North American Numbering Plan Administrator (NANPA) numbering guidelines. Invalid Originating ANI means any ANI that’s not a domestic U.S. or Canadian phone number. This also includes ANIs that are missing, manipulated, unidentifiable, or from unallocated prefix ranges.

How do I avoid having my calls to Australia blocked?

The following types of calls to Australia are subject to being blocked:

  • Calls without a CLI (a-number)
  • Calls with an invalid CLI (a-number that doesn’t conform to International standards or is an invalid number length)
  • Calls with an Australian (+61) a-number
  • Calls with a CLI that’s known to be a source of Spam

Please ensure that all traffic destined for Australia abides by the above criteria. Callers not adhering to these rules may be at risk of blocking without notice. 

Note: Calls from destinations outside of the U.S. aren’t supported by our international product. Bandwidth only supports origination calls from domestic U.S./Canadian numbers conformed to the E. 164 format.
