CDR duration of a call http://developer.cisco.com/c/message_boards/find_thread?p_l_id=&threadId=5011439 2013-05-26T00:28:37Z 2013-05-26T00:28:37Z Giorgio Zanoni http://developer.cisco.com/c/message_boards/find_message?p_l_id=&messageId=6491308 2012-09-13T15:26:09Z 2012-09-13T15:26:09Z

Hello, Drilon Jahiri. I'm developing a tool to analyze CDR compact log. Maybe could you help me to understand how calculate call duration, etc? Please let me know.

Ok thank you.That was exactly what I needed...because disconnect time is same in both but the ft time it`s different for some seconds.So answer leg is leg I need. Thank you again

Drilon jahiri 2012-01-25T23:18:50Z Yaw-Ming Chen http://developer.cisco.com/c/message_boards/find_message?p_l_id=&messageId=5061881 2012-01-25T23:08:16Z 2012-01-25T23:08:16Z

I think we should have same value in both line if not, I will get ft from answer (incoming leg) as it happens earlier and disconnect-time from originate (outgoing leg)

Yaw-Ming Chen 2012-01-25T23:08:16Z Drilon jahiri http://developer.cisco.com/c/message_boards/find_message?p_l_id=&messageId=5063197 2012-01-25T23:01:26Z 2012-01-25T23:01:26Z

No for a TWC there are two lines...and yes these lines have the same fcid.This is for a TWC (not CXFER, BXFER,CFNA,CFBY etc).But there is only one problem: as I mentioned ...one leg is "answer" and one another "originate" ...so I don`t know wich leg (row) to get for calculating"h323-disconnect-time - ft". Anyway Thank You Indeed,

Drilon jahiri 2012-01-25T23:01:26Z Yaw-Ming Chen http://developer.cisco.com/c/message_boards/find_message?p_l_id=&messageId=5061687 2012-01-25T22:57:57Z 2012-01-25T22:57:57Z

I do understand your frustration. I know it's hard to interpret CDR file. For a TWC I think there are 4 lines. You may see the same value of attribute in multiple lines. The logic should be in the file I attached but I don't quite remember. I do remember sometime we need to follow "fcid" to navigate around all lines. Sorry that couldn't help you further.

Thank You and forgive me for all these questions but I really am stacked and I don`k know what to do anymore. OK you are sure that "h323-disconnect-time - ft" is talking time ? my problem now is wich row to get this"h323-disconnect-time - ft" value (answer or originate).If you have answer please help me and if not than THANK YOU VERY MUCH.I Approciate your help.

Drilon jahiri 2012-01-25T22:31:52Z Yaw-Ming Chen http://developer.cisco.com/c/message_boards/find_message?p_l_id=&messageId=5061269 2012-01-25T22:20:10Z 2012-01-25T22:20:10Z

Like I said, it's been a while. I might have asked the same question before, why not "h323-disconnect-time - h323-connect-time" ? But I don't remember what answer I got. All I can tell you is that I didn't make up "h323-disconnect-time - ft" this value. I'm instructed by the Cisco team who developed CDR file. You may notice that we use a lot of attributes in feature VSA that might support that "ft" is a important time stamp By the way I remembered to CDR "answer" means "incoming" "originate" means "outgoing" Calling party -------------------> GW ----------------------? Called party answer originate

Yaw-Ming Chen 2012-01-25T22:20:10Z Drilon jahiri http://developer.cisco.com/c/message_boards/find_message?p_l_id=&messageId=5062627 2012-01-25T21:44:40Z 2012-01-25T21:44:40Z

...well I analyzed your fjava Script and as I can see you used   h323-disconnect-time  -  ft_time to calculate the time of talking between two numbers.   I am making a application with C# and SQL.I am, parsgin my csv files to a sql table and then in that table I am filtering with a store procedure and filktered data I am saving in another table in wich I save:   Call_ID,CallingNumber,CalledNumber,SetupTime(same as ft_time),ConnectTime.DisconnectTime...and from this table I will make something else(report or whatever).   All I need to know in wich row should I calculate h323-disconnect-time  -  ft_time (and are you sure that I shouldn`t use  h323-disconnect-time  - h323-connect-time ) , because as I mentioned in other replys, for onw TWC call there are two records(one answer record and one originate record, this is in CallOrigin field).   So...ft_time it` different (for some seconds) in answer record and in originate record.   Watch my CDR file atached if you have time, please.

I have attached Java script you can take a look if you are interested. It's done long time ago might not perfect but every field of calculation was instructed by Cisco dev team.

Yaw-Ming Chen 2012-01-25T20:05:03Z Drilon jahiri http://developer.cisco.com/c/message_boards/find_message?p_l_id=&messageId=5058286 2012-01-25T19:55:23Z 2012-01-25T19:55:23Z

...also one another problem is that for one call CDR generates two rows (one row is originate and one row i answer) and in two rows there is a different ft_time (113) ...so wich should I chose as exact time?

Drilon jahiri 2012-01-25T19:55:23Z Drilon jahiri http://developer.cisco.com/c/message_boards/find_message?p_l_id=&messageId=5058282 2012-01-25T19:52:27Z 2012-01-25T19:52:27Z

...in fact : h323_disconnect_time - ft = talking time between two numbers Sorry for this mistake :)

Drilon jahiri 2012-01-25T19:52:27Z Drilon jahiri http://developer.cisco.com/c/message_boards/find_message?p_l_id=&messageId=5058279 2012-01-25T19:49:09Z 2012-01-25T19:49:09Z

Thank You for this reply Yaw-Ming Chen.Are you sure because as I could see ft(113) is feature invocation time and this is equal to h323-setup-time(7) and I have tried calling a number and after talkign for a while I generated a CDR and for this talking it the talkig time was: Dosconnect time - connectTime(I can be wrong and I`m not sure yet about this). If you are sure about your answer then I will use : ft - h323_disconnect_time = talking time between two numbers. I still can`t understand why there is a h323-connect-time and a h323_disconnect_time ??! Thank you for your interes in this post.I need your help.

I used Java script to to this before it's been a while I don't know the index of attribute is still the same but attribute should be the same. Use "ft" from Table 8 Attributes in Feature VSA (page 22) and "h323-disconnect-time" (page 10) var ft_time = 113; var h323_disconnect_time_idx = 10; //return the duration of call function duration(str1,str2) { var diff = (str2- str1)/1000; var min = diff / 60; var sec = diff % 60; var call_time = Math.floor(min)+' Min and '+sec+' Sec'; return (call_time); } duration(data[ft_time],data[h323_disconnect_time_idx]);

well I have read all the documentation offerd by CISCO but all I need is a little help in that file to calculate duration because I don`t know wich row of CDR to read as a start time and wich as end time of a call.There is a chancing for some microseconds. Well anyway if you could give me any contact from your experts to help me I will appriciate it because I really need this help.   I can`t contact Cisco TAC because I don`t have a user with this privilege on CISCO.     Than you!

Hi Drilon, Please refer to the following document http://www.cisco.com/en/US/docs/ios/voice/cdr/developer/guide/cdrcsv.html If you have further queries you could consult Cisco TAC for this as we don't have CDR experts.in this forum. Thanks, Anusha

Hi All.   Please could anyone help me to calculate duration of calling from a number to another number because I am reading about this for about 1 week and still can`t calculate. For one call I am just interested in calculating duration when a calling number calls a called number until the close of connection. I have some CDR files wich I am trying to analyse. For wxample a TWC call is always reorded in two rows of CDR but if there is any CFNA or CFA or any other feature the call is recorded in a lot of fields     In atachement is a sample CDR file that I am trying to analyse and could you please tell me how to calculate duration of a call, Calling number, Called number etc.
