Abstract
Call detail records (CDRs) that are generated by different elements of an IP telephony system in connection with the same communication can be matched to one another using timing information contained in the CDRs. Other information in addition to timing information, and which is present in two CDRs relating to the same communication may be used in conjunction with timing information to match CDRs from the same communication.
