Actually you can't get any guarantees in case of PSTN too :) 2011/5/19 Steven Ayre <steveayre@gmail.com>
There's no way of knowing really.
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.
All I can tell you is 44336 is a valid UK phone number prefix ( http://en.wikipedia.org/wiki/03_numbers).

Today, after my phone rang with a CID of (443)366-9222, I took a look at /var/log/freeswitch/freeswitch.log file on my Seagate DockStar (excerpted below). What caught my attention is the last line which shows two numbers, namely 4433669222 and 4016488312. The question I have is if 4433669222 is a spoofed number?
