Common recording methods

Passive tap trunk side recording
This method taps directly into a T1 or E1 line to record all incoming calls at
the demarcation point before going to a switch. In general, passive tap
recording caches a recording of the entire contact on the recording system. If
an event does not trigger storage of the recording within a specified period
of time, the cached recording is deleted from the system.
Passive tap trunk-side recording requires a physical connection directly
between the demarcation point and the switch system. The physical
connection is implemented by placing a junction box on the inbound T1 or
E1 line. One junction box is required per trunk to be monitored. Further, two
T1 or E1 voice board spans are required per junction box to capture voice
data from both the customer voice channel and the agent voice channel. The
following diagram illustrates a passive tap trunk-side configuration
