how can I trace who is calling outbound to a public number?

[zhulin211]

Hi, a PSTN user is receiving calls from my company, but when he answer the call, he is hearing "Beep", it seems like a fax machine from my company is sending fax to him, and call shows up as my company main number. I dont have CDR, then do I have some ways in order to trace the call?
thanks.

I am confused....

How does a PSTN user (typically has no calling line id) know that a call with a "beep" is from your company?

Call trace works on individual ends. This may not be a good option.

If you have digital services (T1 / E1 etc, you could try a D-Ch messaging, leave it run for a while then search on the called number.

thanks DFKSydney.
when we call out, we send company main number to PSTN. we do have T1 to Bell, can you please send me how to set up this kind of call traceÉ

Its not a call trace... but a dynamic print.

I am in APAC. This may be relevant to you.

LD 96

STAT DCH (ent) This will give you the D-Channel numbers. The more the T1s the more the numbers

ENL MSGO (the DCH number) (ent)

You may need to do this a number of times

At this point, you should be capturing the output to a file. Over a period of time, you should ventually get an entry indicating that a call is being made to the B party. This should also include the originator of the call.

When finished...

DIS MSHO (The DCH number) (ent) You may need multiple entries here as well.

another thing I do is if i answer a call and here the fax tones I transfer that call to my fax machine. This way most of the time it will show the fax number that the call is comming from on the fax itself.

I have done the dynamic print, but it seems like there is no originator.

The CALLING 905883xxxx is my company main number, the CALLED 416357xxxx is my BB, but I can not find ext originator.

thanks.

Your fax machine has probably already timed out from retries (ours are set to 5 I think). Depending on how many fax machines you have you can either physically go to them and print the call activity report off them and look for that transmission attempt to that residence number or just forget it as someone just accidentally entered the wrong number and chances are that the fax timed out and will not transmit to that number anymore.

Oh and wait until a low life telemarketer illegally uses your Caller ID name and number to process calls. That's fun to try and explain.

thanks, what I traced was not fax machine, I traced my blackberry. but it seems I can not find extension who originated the call by this way. did I miss something?
