I have 2811 router which i want to use as cisco cme and what to register ip phones with it. The issue is i have not good storage in that router so that i can place all ip phone's firmwares and configurations. Thats why i want to configure an external tftp server so please guide me.
Specially when i will make any change in phones configuration how it will update the configuration file on external tftp server.
Waiting for positive immediate response.
