Built-in Bridge (BIB)

A conference capability inside Cisco IP phones used for barge and to fork call media to a recording server.

Definition

When recording is enabled, the phone's BIB sends two additional RTP streams (near end and far end) to the recorder through a SIP trunk defined in the recording profile. BIB must be enabled on the phone for both barge and recording. It avoids needing network-based recording hardware.

Example

Enabling BIB and a recording profile on the agent's line allows automatic recording of every call.

Exam tip

BIB recording doubles the phone's upstream media traffic for recorded calls.
