Hi,


We have installed 2 CCM's (One Publisher and the other as Subscriber), we want to use the one of the CCM as backup for the other. So we had configured both the TFTP server IP address in the DHCP scope (which is being used by IP Phones).


Now all most all the phone took both the TFTP server address from the DHCP server, however few phones are not taking both the TFTP server address its taking only one TFTP server address and its showing it on "TFTP Server 2" (The "TFTP Server 1" option is blank)....


I had refered the following url and tried all things which were mentioned in it... but..still those few IP phones are taking both the TFTP server ip address from DHCP.....

Are you using more than 1 DHCP server ? I think you can statically insert the TFTP 1 address to the phone manually for temporary.
