15 seconds to trace a call - myth?

Does a call really have to be 15 seconds long in order for police to trace it? Or is this just another Hollywood myth? I don't see why the length would matter. It seems that the people who write for Sopranos disagree though.

my caller id works immediately... i guess tracing would have to be more accurate

Yeah, that too. I don't understand why tracing would be different. Unless the caller is using *67 (private), but i'm not sure whether that erases the log or just makes it unavailable to the person on the other end.

Yeah, I never thought of that. My caller ID displays the phone number of the caller on the 2nd ring! :Q

Don't you know from watching movies that it depends on how many extra satellites the call is routed through? ;)

Are you planning to do something naughty and hoping you won't get traced? Santa won't like that.

It's still logged by the phone company, so harassing an ex-GF is probably not a wise idea.

From Carver, Co, MN Sheriff Dept:
Everyone has the capability to trace a call. Calls can be traced by using *57 after a nuisance call has been received; however, the procedure may vary between phone service carriers.

Sprint/United Telephone customers: Once a call has been traced, you should contact Sprint/United Telephone at 1-800-788-3600 to report the date and the time the call was received. Sprint/United will then send further information to you. You should then contact our dispatch center at 952-361-1231 to report the crime. At that time, the law enforcement officer will inform you of the trace procedure. Only law enforcement has access to the calls traced and a report has to be documented. Once the report has been taken, it will be forwarded to the Criminal Investigation Division for follow up.

U. S. West customers: Once a call has been traced, the customer should contact GTE at 1-800-426-7621 to report the date and the time the call was received. GTE will send further information to the customer. The customer should then contact our dispatch center to report the crime.

Vista customers: Once the call has been traced, the customer should contact Vista at 952-435-4739 to report the date and the time the call was received. Vista will send further information to the customer. The customer should then contact our dispatch center to report the crime.
Internet "Search" is you best friend - Try Google. ;)

you get your caller id number (or if you don't have that press *69 - the phone company reads the number back to you!)

do a reverse search on the internet

i did it myself with a crank phone call

grand total to find the name and address of the person screwing with me was about 3 minutes.

something delightful about calling a crank caller at his home, addressing him by his first name, and tellinh him some people will becoming over to "knee-cap" him if he calls again..it gets their attention (and the calls stop!)

I do research on cell phone infrastructures (which basically means the SS7 network). That's the same network that is used to connect all your voice calls.

"Tracing" like the cops do is instantaneous. Think about it: Some computer, somwhere, has to know where to route your voice traffic, right? (it's called a "trunk" in the biz). So if the switching center has that routing information, why couldn't it be obtained instantly? Once you know where the trunk is terminated (i.e. who is being called) then it's just a matter of looking up in some sort of location directory where the address is (and jeez, it's not like the freakin PHONE COMPANIES have that sort of information on hand, is it? No, they just have psychics in those vans that sense where you live).

That "we didn't get it...he wasn't on the line long enough" crap is just that: crap.

SS7 routing address (and I forget my acronym for this...it's a TLDN for cell phones, don't remember for POTS) plus service provider address lookup = traced call.

Simple as pie.


For cell phones it's a little harder. In fact, the reverse is true. To the best of my knowledge, it's not really possible to "trace" them. Cell phones are merely connected to a "location area" (registration zone, or whatever else you want to call it). When you get a call, all the base stations in that zone (which is governed by one VLR/MSC pair..which you don't really need to know =]) are paged, and if the call is for you, you answer.

So getting correct geographic information on a cell phone is really hard. During a hand off (when you cross the boundaries of two zones/stations) you might be, briefly, connected to two stations at once, but you need three points to triangulate. This, again, AFAIK, does not happen.

Just in case you were wondering....

schizoid, somehow i sense that Pablo Escobar would disagree

lol, so true. Although iirc, the method was a little spotty, could 'only' trace to like a half mile square area....then they saw him through the window, and the rest is history :)

Well, I don't think it means the person would be calling from a regular phone.. any old caller id will pick that up. Maybe it means it takes that long to trace a cellular phone or a pay phone.. to narrow it down to a general area of where it is being used

Pablo was the target of probably the world's largest manhunt (like Carlos the Jackal).....he was a BIGTIME drug dealer in Brazil(?) or Veneuzla, or somewhere down there :)

Anyway, he at one time blew up a passenger airplane...we sent, unofficially of course, delta force guys along with other black ops troops, to go and hunt him down. They were trying to track him down via cell phone, and they got it narrowed down to a neighborhood (this is after many months), and then as they are driving, they see him in a window, and lay out a MAJOR assault...anyway, for a VERY interesting read, see the book "Killing Pablo"

i recently read an article about this and it doesn't take a long time anymore. the term "tracing" refered to the operators literally tracing the phone lines and it took quite awhile. imagine a tangled bunch of cords and you have to find the other end of one. now it's all done by electronics and it's fast.

Yea, and if it is a home/ pay phone, then they have the ability to keep the voltage runiing after a hang-up, and if the voltage is still there, then the call won't end. That wya they have as long as they need.

If he was making a call, then sure, you know EXACTLY which base station he's connection to. And guess what kiddo...a base station covers...oh...say...hmm...about...COULD IT BE A NEIGHBORHOOD?

Otherwise, the only way you could pinpoint his location is the "heartbeat" of a cell phone which periodically connects to the basestation (this is another form of a location update, except that the location isn't changed). This isn't done all that often. My guess is that homeboy was making a call. Like I said, if you're making a call, you're toast.

But it's not like I have a masters degree in all of this stuff or anything....
