What is the format of the U1900 CDR?
The U1900 only provides CDRs in binary format. The size of each CDR is 240 bytes. The charging mode and rate are determined by the customer's own charging system. Currently, you can query CDRs on the BMU or through a third-party CDR system. The UC solution opens FTPS interfaces on the CDR server to provide raw call records for third-party systems.
