Scenario 4 - VoIP Monitoring
The NAM can collect the control and diagnostic messages sent from IP phones to the Cisco Call Manager
application and provide network engineers with valuable information about the voice aspects of a network.
Because Dean has configured the Catalyst 6500 Series NAM to SPAN the port connected to the Cisco Call
Manager application, he will be able to collect all traffic from IP phones located in the various workgroup
access switches to the Cisco Call Manager. It is important to note that to use the voice monitoring feature of
the NAM, you must SPAN a port or VLAN that will contain the Cisco Call Manager traffic. Also, the Cisco
Call Manager must have “Call Diagnostics Recording” enabled for IP phones to send diagnostic statistics to
the Cisco Call Manager.
