Free Online CDR/TAP3 Decoder

This online decoder allows decoding of ASN.1 encoded CDR/TAP3 files. No ASN.1 syntaxes are required. Simply choose the CDR/TAP3 interface you want to use and supply the data.

CDR decodings are available for proprietary CDR descriptions (Ericsson, ZTE, Huawei) as well as for GSM-Association TAP3 and 3GPP TS 32.3298.

Supported CDR encoded input is raw (binary) format. The generated output is in XML format which allows easy reading and processing of decoded data.
