asterisk users - May 2005 - DVG-1120S does not show callerid Name and resets time

Hi,
I am having problems with callerid name and the time with my
dvg-1120S. Every time I receive a call, it reverts the phone to
January 1st 12:00am. I've looked everywhere in the browser and telnet
configuration to change this.

Also, it never shows the name of the caller. I've even tried forcing
the caller id info using SetCallerID, but it still doesn't show the
name.

Any suggestions?
Thanks,
-Ryan
