Hi Siva,

The version looks fine, is it possible for you to send a copy of your config where the ATA is configured? eg. ephone, ephone-dn etc? from there we can start to verify all the possible problems.

type ata

button 1:59


ephone-dn 59 dual-line

number 2200

Hi Sivakumar, have you specified the actual tftp binding command for the ATA image as tftp-server flash:ATA030100SCCP040211A.zup or the appropratie path on the flash?

If you debug tftp events, and unplug and plug the ATA back in, do you see any events logged regarding the ATA?

Here is a document for troubleshooting IP Phone registeration in CCME, you may or may not find it helpful:-

Hope this helps

Allan's suggestion is a good one as well, also in addition in troubleshooting the ATA registration to CME, can you also verify and assigned all ip address, subnet, gateway and tftp url in your ata statically just to make sure that it has all the details.

The problem has been fixed up when we change static ip to DHCP configured on the switch.

Thanks to everyone ..
