Call Records Service
Overview
A Call Detail Record (CDR) contains information about a processed call.
This information can include the identity of the calling and called parties,
the duration of the call, and the type of call. CDRs can be imported by

In a VCX system, CDRs can be generated by a call processor or by an IP
Messaging server.
