Hi,

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

Symptom:

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

Conditions:

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

Workaround:

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)

Please rate useful posts...

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.)
