Actually you can't get any guarantees in case of PSTN too :)<br><br><div class="gmail_quote">2011/5/19 Steven Ayre <span dir="ltr"><<a href="mailto:steveayre@gmail.com">steveayre@gmail.com</a>></span><br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
There's no way of knowing really.<br><br>You can send any CID you like in SIP. They might own 4433669222 in real life, they might not. You only really get a guarantee it's genuine if it's coming off the PSTN.<br>
<br>All I can tell you is 44336 is a valid UK phone number prefix (<a href="http://en.wikipedia.org/wiki/03_numbers" target="_blank">http://en.wikipedia.org/wiki/03_numbers</a>).<br><br>-Steve<div><div class="h5"><br><br>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Today, after my phone rang with a CID of (443)366-9222, I took a look at<br>
/var/log/freeswitch/freeswitch.log file on my Seagate DockStar (excerpted<br>
below). What caught my attention is the last line which shows two numbers,<br>
namely 4433669222 and 4016488312. The question I have is if 4433669222 is a<br>
spoofed number?<br>
