Happy holidays to all. Quick question with regard "Text/SMS" messaging. I know this is not really the place to ask, so forgive me for bending your eyes. It appears there's really no easy way to determine the origin of a text sent to a cell, at least as far as I can see without involving the provider(611) Any quick links/ideas as to where to research this? Perhaps something obvious I missing? And yes, I tried, lmgtfy.com (: Thanks in advance, and happy holidays/Xmas/New years to all, -Joe Blanchard

For shortcodes, Neustar provided a list: https://www.usshortcodes.com/csc/directory/directoryList.do?method=showDirectory&group=all For regular cellular numbers, the Wireless Amber Alert site is popular amongst MVNO (e.g. prepaid) users to find out so they can use the email-to-text gateways: http://www.wirelessamberalerts.com/ (You don't actually sign up, just enter the number and then it will tell you the carrier.) For landlines/VoIP/etc. Google should be able to tell you at least the city/state. Though it's rare that you will get a text from a landline, it is possible. Andy

I could be wrong, but I think the actual question was "is it realistic to assume a text to a cellphone came from the number it *says* it came from?" and I think the answer is "no, there are a few ways to spoof it". Received SMS messages are probably not evidentiary, absent a report from the receiving carrier of the message traffic log involved, which would itself be hearsay unless someone testified about it.

Thanks Jay To add to this Sleepy here but a quick script ((linux for you windows guys) [root@sumless3 jgb]# cat send_text.sh #!/bin/sh echo "go" # Server's IP address # IP_ADDRESS='some_smtp_relay.com' mf="mail from:" rp="rcpt to:" echo $mf (sleep 2 ;\ echo "HELO guess.net";\ sleep 2;\ echo $mf " <adminops1@blah.net>" ;\ echo $rp " <44421211@tmomail.net>" ;\ \*Bogus return addy *\ sleep 4;\ echo "data";\ sleep 3;\ echo "Subject: Merry Christmas!.. ";\ echo "From: Spammerr";\ echo "To: YOU";\ echo " SPAM SPAM blah blah... - sleep 2;\ echo ".";\ sleep 1;\ echo "quit";\ sleep 2) | telnet $IP_ADDRESS 25 #| telnet $IP_ADDRESS 25 exit Seems to put them thru, and unless you the providers Tier3-4 suport theres nothing you can do... Only a matter of time till something does a count(n) in C or else... Cheers, Thanks Andreww! -Joe On Fri, Dec 17, 2010 at 1:14 AM, Jay Ashworth <jra@baylink.com> wrote:
