Cisco Unified CallManager 4.2(3) Call Detail Record Definition
OL-10659-01
Call Types
Transfer with Consultation
Transfer with consultation essentially acts identical to transfer without consultation, except the duration
of the middle call is not zero.
As with a transfer without consultation, Cisco Unified CallManager creates three CDRs. The first CDR
reflects the call between the original two parties (A and B), the second CDR represents the consultation
call between the transferring party (A) and the new party (C), and the final CDR reflects the call between
B and C.
The following tables contain three examples:
• A—Call from extension 2001 to a PSTN number, talking for 120 seconds.
• B—Extension 2001 places the PSTN call on hold and calls extension 2002, talking for 30 seconds.
• C—Extension 2001 completes the transfer, dropping out of the call, leaving a call between the other
two parties.
Precedence Calls (MLPP)
Precedence calls take place the same as other calls except the precedence level fields get set in the CDR
record. Also, when a higher-level call preempts a call, the cause codes indicate the reason for the
preemption.
The following table contains an example CDR for this scenario:
• User A calls another IP phone by dialing a precedence pattern (precedence level 2).
• User B calls another IP phone by dialing a precedence pattern (precedence level 3).
• User A receives a precedence call from another network (precedence level 1).
• A higher precedence level call preempts the call.
