Cisco netflow

Hello,

I have a 2801 router, which has a few ip phones connected to it. and this 2801 is then connected to a switch where i also hav a couple other devices thus forming a LAN. i have enable cisco netflow on the 2801 box and on the fastetheret interface. however im not sure how i can obtain the flow records. I am not trying to export this netfow data to any server or network analyser. i just want to see the netfloe data that is accumulated through the CLI. i try using the command show ip cache flow it does display the data. but i try making calls to the ip phones that i have connected to the 2801 from outside and i dont get any data about these calls when i check the netflow cache. how can i use netflow to obtain this information.

Go through this "Cisco IOS Flexible NetFlow Technology Q&A" (What is a Flexible NetFlow Flow Monitor) and use the "Configuring NetFlow " document for configuration.
