Answer 2

In that context, it is most likely a Call Detail Record, as the clients are Vonage, Verizon, etc.

Answer 3

Hi

It is the Call Detail Record. A call between points A and B might get routed through a few switches and for each leg of that call a CDR gets generated. The final CDR would be a correlation of the CDRs from each leg. A CDR contains information pertaining to a call, such as:

• Calling Number
• Called Number
• Point Codes or Switch codes of the source switch
• Point Codes or Switch codes of the terminating switch
• Trunk Access Code
• Time stamps of different events during call setup and call tear down

There are lots of other fields in a CDR and most of them vary depending on the standard being used. For example- Most of the fields mentioned above pertain to an ISUP call. The CDR for a GSM/GPRS call would differ.

I hope this helps.

cheers
