Telecommunications Act 1997 applies: "The ACMA, carriers and carriage service providers must do their best to prevent telecommunications networks and facilities from being used to commit offences." I'd say the telcos are due to be put on notice regarding the use of CLID spoofing. Kind regards P

SPF / DKIM for phone calls? That would be great, but what about calls that are forwarded by systems that originate from a third party, you want to maintain the original CLID during forwarding so you overstamp it to the outbound call as it's forwarded.

There is work going on in the IETF ART WG with RFC7340 and RFC 8224 leading the way. I'm not convinced we will get widespread implementation. Looks like caller ID spoofing is likely to persist for a while... Narelle On Tue, 1 May 2018, 8:24 AM Nick Stallman wrote: > My 2c, it is really tr

My 2c, it is really trivial to get a voip service with zero caller ID validation. I've got one, and while we have a legitimate purpose for it, it only took a single email to request validation to be turned off and it didn't even cost anything. Works perfectly with all telcos in Australia, I've

The problem is that they are now using genuine third party numbers. And the poor ducks that actually own them end up receiving a million calls in response. Please everyone - make sure you secure your call servers and ensure good authentication!! Not to mention enforcement of number ownership in y

Hi folks we may be hearing a rise in the incidence of VoIP calls faking their caller ID for the purposes of spamming and scamming. Consumers check the caller ID on their hand CND and accept the Australian sourced number, only to find it is a complete scam. This is often tied to the 'missed call sc
