It’s not really about security and authentication of VOIP infrastructure. It came about because people want to set CLID on outbound calls via carriers that don’t own their numbers. In some ways it’s consumer/business friendly BUT abuse leads to phone calls being a trashfire. In the US it’s meaning that some carriers run all calls through some validation and present some info about whether it’s real or not or the likely actual origin. T-Mobile are doing this - super helpful as you get info on whether it’s a scam or not. HIGHLY recommend Australian carriers get onto this. It’s cut down the amount of dodgy calls in the US a lot recently.</div><div><br class=""></div><div>MMC</div><div><br class=""></div><blockquote type="cite" class=""><div class=""><div class=""><br class=""></div><div class=""><br class=""></div><div class="">Narelle </div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""><div class="gmail_quote"><div dir="ltr" class="">On Tue, 1 May 2018, 1:23 AM Chris Watts <<a href="mailto:Chris.Watts@techanalysis.com.au" class="">Chris.Watts@techanalysis.com.au</a>> wrote:<br class=""></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex" id="gmail_block_quote0">

say that in my experience, most of the time it's not
spoofed CID or ANI, rather a compromised set of SIP
gateway credentials. Once in, they either don't
bother setting CLIP (because it's a scam call) or
they set it to something that the caller is likely
to pick up - local area code prefix or similar. The
side effect of this is the usual network security
approach, rather than telephony security - setting
up fail2ban, choosing strong passwords, whitelisting
source IP's that you know are cool, blacklisting
certain countries IP ranges (India...) yada yada.</span>

<div class="">Hi folks</div>
<div class="">we may be hearing a rise in the incidence
of VoIP calls faking their caller ID for the
purposes of spamming and scamming.</div>
<div class=""><br class="">
</div>
<div class="">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 scam' but now
they are using genuine Aussie phone numbers
and the genuine owners aren't happy.</div>
<div class=""><br class="">
</div>
<div class="">From my rusty experience at setting up VoIP
systems, you should be able to impose filters
on incoming calls at the network level here
the number doesn't match the source - can
people please give me a clearer update on this
from the trenches?</div>
<div class=""><br class="">
</div>
<div class="">What are the good housekeeping steps for
network operators?</div>
<div class=""><br class="">
</div>
<div class="">Off list please and I'll summarise the
responses,</div>
<div class=""><br class="">
</div>
<div class="">thanks in advance</div>
