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>Hi folks</div>
<div>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><br>
</div>
<div>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><br>
</div>
<div>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><br>
</div>
<div>What are the good housekeeping steps for
network operators?</div>
<div><br>
</div>
<div>Off list please and I'll summarise the
responses,</div>
<div><br>
</div>
<div>thanks in advance</div>
