I configured my ethernet NIC card of my Laptop with CCM 5.1 for the use of IP Communicator. I was away and needed to use the IP Communicator. I used my wireless NIC card through a VPN connection and it worked. My question is how did this work? The only Mac Address configured in CallManager and associated with my office extension was the Ethernet Mac Address and not the wireless one. Could you please shade some lights on this and let me know how did this happeb to work?
