I took a packet capture from the Cisco IP Phone 7941G. When i analyze them, it was all like ARP, XID, TCP, STP, etc packets captured. But i didn't find any RTP or Skinny or any voice related packets.
The procedure i followed was
"Enabling the Span to PC port feature on the 7941, 7961, or 7970 phone. In order to do that, find the phone in CCM and, on the Device page at the very bottom in the Product Specific Configuration Layout, enable Span to PC Port and reset the phone".
I used Wireshark. FYI. I have disabled all the firewall and monitoring tools in the PC while capturing.
Can u pl suggest why the relevent packets are not being captured.
