You can connect to the IP phones using a web browser :-

http://

Got to device information section and the mac address should be displayed. For more info see :-

hi

i have tried connecting the phone through browser, but its not happening.

is there anyother way for this problem.

All phones run CDP. Your switch should definitely be running CDP. Give a show cdp neighbor or show cdp neighbor detail to get the mac-address and IP address of IP phone. This command will also show the port on the switch where each individual phone is connected. Hope that helps!
