Answer 1

How about this CDR decoder for Ericsson ? http://code.google.com/p/cdr-decoder/

Answer 2

There is no such thing as a standard structure for CDRs in mobile telephony networks. Find out which network elements you are going to talk to and look at the documentation.

Mobile telephony networks usually deploy a component called "mediation device" which is specialized on parsing and unifying the CDR formats emitted by the various actually deployed network elements. Companys make money with this.

If you are lucky you might get xSV files with vendor-specific columns and column order. If not you might get e.g. ASN.1-encoded or binary files with proprietary formats.
