Cisco Unified CallManager 4.2(3) Call Detail Record Definition
OL-10659-01
Call Types
Call Hold and Resume
When a Cisco Unified IP Phone places an active call on hold and then returns to the call without making
a second call, the CDR reflects the entire duration of the original call as an uninterrupted call.
The following table contains an example of a call from Cisco Unified IP Phone 2001 to Cisco Unified
IP Phone 2309, placing the call on hold, and resuming speech part way through the call:
Transfer Without Consultation
A single CDR cannot show call transfer, which is too complex to show. Each time that a call is
transferred, the Cisco Unified CallManager terminates the CDR for that call. The process of transferring
a call, without consultation, involves the creation of three CDRs. The first CDR reflects the call between
the original two parties (A and B), the second CDR represents the (zero length) call between the
transferring party (A) and the new party (C), and the final CDR reflects the call between B and C.
No CDR reflects the time that a call is on hold. If a call is through a PSTN gateway, the call accrues
charges that are not reflected in the CDRs while the call is on hold.
The following table contains three examples:
• A—Call from extension 2001 to a PSTN number, talking for 120 seconds.
• B—Extension 2001 initiates a transfer without consultation (hence the duration is zero) to extension
2002.
• C—Extension 2001 completes the transfer, dropping out of the call, and leaving a call between the
other two parties.
