Determine who made outbound call

[mastang13]

I have an internal person who is making outbound prank calls to a cell user. The cell user can see our main number display on the cell phone but I can't seem to find out were exactly this call is comming from. I've checked CDR and nothing comes up. We have an Opt 11. Any idea's?

I would see if there is a "minimum call duration" setting in the CDR system - that is set just a a little longer than the prankster might be speaking.

The other idea is to perform your "dialed number search" with a wider "wildcard" search.

For example if the cell phone was "212-555-1212" is it possible to search on ???5551??? or some variation.

Years ago, as a young phone wizard, whenever I was at a hotel, I just made calls and kept dialing digits - 10 or 20 of them. That often resulted in a confused call record that never made it to my room charge. Yet the call connected just fine.

Other ideas: Is this person at the switchboard? Those "DNs" in a typical 3 console PBX might be "001 thru 003"

are you looking at raw data? and do you have cdr yes on all routes? and you can have cdr collection turned off on just a single station..

could it also be someone spoofing the caller ID throwing your main number as CallerID with one of those sites or calling cards that do that?

or one of those...?

how would i go about checking cdr is turn on on all routes as well as call duration? raw cdr data get's collected by third party and we get readable reports from them is there a way i can manually search the numbered dialed in the switch?
i'm a data guy and all i know how to do is add's/moves and changes on our pbx.
thanks for the tips

i don't see a short call duration in the cdr data.. ld 21 prt cdr.. to check all routes, ld 21 prt rdr cust 0 return, that prints all the routes, check for cdr yes in each route. some switches only capture cdr for ld, or one local route may not be marked, so at least check,, the min call factor is not usually a raw data feature but an otm or tabs or another app that prices and sorts calls

It is an optional setting in many CDR software programs - that is what I meant rather than CDR_DATA. The provider may drop short calls in this case though.

There will be a buffer box somewhere on the premise the service bureau connects to to poll the data. If you can ask them if they will search the raw data or if you can get the raw data, you may find the call

You may not be collecting data for local calls, i don't for my sites.

One thing you can do is go to LD 90 and block your system from being able to dial that cell number.

 

[SStieferman]

I know about ld 90 to block calls, but is there a way to do a translation so that the number calls and rings a special line at your desk? How would you do DMI on an external number?

I envision a special ringer on an additional extension, a trace key or access to the switch for tracing...

I have not tested this but I just theorizing based on experience. I would make the cell number into and SPN (LD 90) and have it go over a new RLI (LD 86) with an outgoing route. In that entry create a DMI (LD 86-DGT) that would strip all the digits and input a DID (XXX-XXX-XXXX)that is on your phone.

Hope this works for you.

P.S. PRI's would come in very handy for this as it would give you name display (if it is hitting the CO first)

 

[mastang13]

ok CDR is set to yes on all routes except on 2 point-to-point routes to two other remote option 11c that we have and music on hold, paging and voice mail. we have cdr buufer boxes on the other two sites for CDR collection and reporting.
So do i have to turn CDR on the two point-to-point routes?
Also how would i block the cell number in ld 90 can I have an example?

Thanks again for the tips..

Deny a local number xxx-yyyy

REQ chg
FEAT net
TRAN ac1
TYPE nxx

NXX xxx
RLI
SDRR deny
DENY yyyy

USE Xyyyy to out the change.

sorry forgot to mention that the number s long distance, would this still apply? let say the number is 555-233-1414 and is long distance how would i put it in ld 90?

 

[SStieferman]

SWEET - DO THIS INSTEAD HEHEHEHHE.

chicks cell number # xxx yyy zzzz
extra phone in your cube - preferably a 39xx with a missed calls option.
Build this phone with an unused DN and no other numbers on it. Pick some random DN. 45678 for this example

New DMI #10 in this example
LD 86
REQ NEW
CUST 0
FEAT DGT
DMI 10
DEL 17
INST 45678
CTYP NCHG

Change existing NPA in LD 90. Since your users can already dial the number, its in there, you may just have it listed differently...

LD90
REQ CHG
CUST 0
FEAT NET
TRAN AC1
TYPE NPA

NPA 1xxx
RLI ******no change, other calls still go out this trunk
SDRR LDID
DMI 10 ***** from above
LDID yyyzzzz



Make test call to xxx yyy zzzz, your new desk phone should ring.

Thanks lamasu!




Ok to answer your question mastang13

LD 90
chg
net
ac1
npa
1xxx
rli ***** blank (cr)
SDRR deny
DENY yyyzzzz
enter out

hope that helps.
