Call Splitting
Call splitting keeps track of calls where more than two parties are involved. These can be calls that are transferred or conferenced. When any of these situations arise, CDR produces a separate record for each new party involved in the call.
Conference
Caller A makes an incoming trunk call to switch party B (201). They talk for 2 minutes, then B conferences in C (202), and D (203). The entire group talks for another 8 minutes, at which point B drops off the call. This produces a record for segment A–B.
A, C and D continue to talk for another 5 minutes. All remaining parties drop, producing two more records; A–C and A–D. Note that each record shows the incoming trunk ID as the calling number.
