What is Mediation?

  • Files transfers

  • Decodes data that has been encoded by the ASN.1 into the internal standard format.

  • Validate, formatting and conversion data by mapping rule.

  • Aggregates partial CDR belonging to the same session by the CDR type.

  • Correlates different CDRs belonging to the same session.

  • Filters CDRs and their fields according to the systems that need charging data.

  • Create flexible and wide CDR for Business System Software
