There could be a lot of reasons for the phones to un-register. The most common of the random issues would be lose of keepalives. Do u have high traffic on the LAN, different vlans for voice and data, QoS ??

Also, check the firmware on the phones, it would be a good idea to go to the latest firmware

Would also be useful to check for any spanning tree issues.
