Hi Mudasar,

Need more info about the UC520 "hang" situation:

++  Are you able to console to the router at the time of the problem?

++  Are you able to ping the router?

++  Do your ip phones unregister?

++  How frequent is the problem?

++  Can you please attach a show tech from the device here?

Refer to the following link for troubleshooting router hangs:

http://www.cisco.com/en/US/products/hw/routers/ps359/products_tech_note09186a0080106fd7.shtml

If this helps, please rate.
