Display caller number from external to internal

[riverside_college]

Call Manager 9

I have been told that I cannot get logs on who is calling the organisation from outside because we have a call handler. I find it hard to believe that this is true but it came from a professional so I have to accept it. I was asked to provide a list of numbers of who has called the main organisation number which I thought would be easy but obviously not.

anyway, I will try something else

When someone calls a DDI (not main number with menu options etc), the internal phone just displays 'external' as the caller ID. How can I get it so it displays the actual number. I have asked this before and I was asked to be a debug on the router but I do not have the credentials. Lets just say im 90% sure I saw an external number on a users phone at some point in the past year, I just cannot remember where.

How would I go about doing this?

Hi,

I think CDR is answer for you first question, see below on how to read CDR

http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/service/9_1_1/car/CUCM_BK_C28A807A_00_cdr-analysis-reporting-admin-guide91.html

For the second question if it shows external for all users, we will have to get logs from CUCM to find where the Called ID is getting modified assuming your service provider is not sending "external" as called ID for all calls.

I was using CDR but anything from outside to inside that was hitting the main number just showed us null. 

am I pulling these logs using the RTMT?

If CDR dint help, only option you are left with is Call Manager traces. Tough part is they are not easy to read.

See the below series of video to get a hand of it.

Yes for CUCm trace collection you can use RTMT, how -> see below.

Once you collect traces try using an advanced word processing application like Notepad++ to search through file, you will get to know how in the video series above.
