You may have problem with the ATA firmware. I have touched this also. Manuali upgrade it with newer firmware.

Other reason can be the Voice Vlan.

1. Firmware in ATA is SCCP? It can be H323, so you must to upgrade firmware to SCCP.

2. I saw some problems with registering of ATAs and there was a solution: login to web-interface of ATA and in SCCP configuration in SID0 and SID1 write "." (without quotes)

The protocols that you can use depends on yours call agent. If you have CallManager it is better to use SCCP. You can find packet containing all the information to upgrade cisco ATA. Filename is something like There is detailed instruction in the archive how to upgrade (sata186us.txt).
