I have this problem too.

Can you tell me what firmware the ATA is using?

There is possibly a problem in firmware prior to version 3.

There is also a known bug which may be relevant?:

CSCso94320 Bug Details

TFTP procedure causes ATA reboot


ATA does an unexpected reboot, and see infinite tftp request at preserv log


ATA enables both channel, but CCM disables auto register and only config one channel.


Disable the second channel to stop infinite tftp request

Is there any more information in the CCM trace files (get them from RTMT - Real-Time Monitoring Tool)

Hi Somsak,

Here is the process;

Note By default, both Cisco ATA FXS ports are enabled for Cisco CallManager registration. If you do not want to add the Phone 2 FXS port to Cisco CallManager, you must change the Cisco ATA EPID1orSID1 parameter value to 0 to disable the Phone 2 port. (To disable the Phone 1 port, you must change the EPID0orSID0 parameter value to 0.)

Hope this helps!
