VoIP Analysis

The TALAN provides a VoIP Analysis interface that does not require the

TALAN 3.0

Hardware.

To activate the VoIP packet analyzer select VoIP Analysis from the

(Manual) menu and then

press

START

. The TALAN VoIP Analyzer interface below will appear.

Once the TALAN is correctly attached to the VoIP network, the VoIP traffic (IP packets) can then
be collected, displayed, and analyzed by the TALAN VoIP Analyzer software.
